No worries, help is on its way!

Welcome to advanced images! This page explains even more about the image syntax when editing the wiki. If you want to know more about Formats, Galleries and Links, this is absolutely the right place for it! You also can return to Basic Images or move on to Image Manipulation, if you have missed something or want to know more concerning images.

Format[edit]

The following table shows the effect of all available formats.

Description You type You get
no format specified
Rendered as a floating block: no
Rendered inline: yes
Rendered caption: no
... text text text [[File:Example image.png|caption]] text text text ... ... text text text caption text text text ...
border results in a very small gray border
Rendered as a floating block: no
Rendered inline: yes
Rendered caption: no
... text text text [[File:Example image.png|border|caption]] text text text ... ... text text text caption text text text ...
frameless, like thumbnail, respect user preferences for image width, but without border and no right float
Rendered as a floating block: no
Rendered inline: yes
Rendered caption: no
... text text text [[File:Example image.png|frameless|caption]] text text text ... ... text text text caption text text text ...
frameless and border
Rendered as a floating block: no
Rendered inline: yes
Rendered caption: no
... text text text [[File:Example image.png|frameless|border|caption]] text text text ... ... text text text caption text text text ...
frame
Rendered as a floating block: yes
Rendered inline: no
Rendered caption: yes
... text text text [[File:Example image.png|frame|caption]] text text text ... ... text text text
caption
text text text ...
thumb or thumbnail
Rendered as a floating block: yes
Rendered inline: no
Rendered caption: yes
... text text text [[File:Example image.png|thumb|caption]] text text text ... ... text text text
caption
text text text ...

When the height of an image in thumbnail is bigger than its width (i.e. in portrait orientation rather than landscape) and you find it too large, you may try the option upright, which will try to adjust its size to a more desirable size by reducing the height instead of the width. The alternative is to specify the desired maximum height (in pixels) explicitly.

NOTE:
C4.svg By writing thumb={filename},
you can use a different image for the thumbnail.

Size and frame[edit]

Among different formats, the effect of the size parameter may be different, as shown below.

  • For how it appears when its size is not specified, see Format section above.
  • When the format is not specified, or only bordered, the size can be both reduced and enlarged to any specified size.
  • In the examples below, the original size of the image is 400 × 267 pixels.
  • An image with frame always ignores the size specification, the original image will be reduced if it exceeds the maximum size defined in user preferences.
  • The size of an image with thumb can be reduced, but can not be enlarged beyond the original size of the image.


Format Reduced Enlarged
(not specified)
[[File:Example image.png|50px]]

Horizontal alignment[edit]

NOTE:
C4.svg When using the frame or thumb[nail] formats,
the default horizontal alignment will be right.

Vertical alignment[edit]

The vertical alignment options take effect only if the image is rendered as an inline element and is not floating. They alter the way the inlined image will be vertically aligned with the text present in the same block before and/or after this image on the same rendered row.

Note that the rendered line of text where inline images are inserted (and the lines of text rendered after the current one) may be moved down (this will increase the line-height conditionally by additional line spacing, just as it may occur with spans of text with variable font sizes, or with superscripts and subscripts) to allow the image height to be fully displayed with this alignment constraint.

To show the alignment result more clearly, the text spans are overlined and underlined, the font-size is increased to 200%, and the paragraph block is outlined with a thin border; additionally images of different sizes are aligned:

text top: Hydra intro.png Hydra intro.png Hydra intro.png text

text text-top: Hydra intro.png Hydra intro.png Hydra intro.png text

text super: Hydra intro.png Hydra intro.png Hydra intro.png text

text baseline: Hydra intro.png Hydra intro.png Hydra intro.png text

text sub: Hydra intro.png Hydra intro.png Hydra intro.png text

text default: Hydra intro.png Hydra intro.png Hydra intro.png text

text middle: Hydra intro.png Hydra intro.png Hydra intro.png text

text text-bottom: Hydra intro.png Hydra intro.png Hydra intro.png text

text bottom: Hydra intro.png Hydra intro.png Hydra intro.png text


C4.svg
NOTES:
  1. The "middle" vertical alignment position of the image (which is also the default) usually refers to the middle between the x-height and the baseline of the text (on which the vertical middle of the image will be aligned, and on which usually the text may be overstroke), but not to the middle of the line-height of the font-height that refers to the space between the "text-top" and "text-bottom" positions ; the font-height excludes:
    • the additional line separation spacing normally divided equally into two line-margins (here 0.5em, according to line-height set to 200%) above and below the font-height).
    • the additional line spacing which may be added by superscripts and subscripts.
  2. However, if the image height causes its top or bottom position to go above or below the normal full line-height of text, the middle position will be adjusted after the increasing the top and/or bottom line-margins so that the image can fit and align properly, and all images (including those with smaller heights) will be vertically centered on the adjusted middle position (for computing the effective line-height, the text of each rendered row with the larger font-height will be considered).
  3. The "text-top" and "text-bottom" alignment positions also excludes the extra line spacing added by superscripts and subscripts, but not the additional line-spacing defined by the line-height.
  4. The "top" and "bottom" alignment positions take into account all these extra line spacings (including superscripts and subscripts, if they are present in a rendered line span). When the image alignment constrains the image to grow above or below the normal line-spacing, and the image is not absolutely positioned, the image will cause the "top" and "bottom" positions to be adjusted (just like superscripts and subscripts), so the effective line-height between rendered lines of text will be higher.
  5. The "underline", "overline" and "overstrike" text-decoration positions should be somewhere within these two limits and may depend on the type and height of fonts used (the superscript and subscript styles may be taken into account in some browsers, but usually these styles are ignored and the position of these decorations may not be adjusted); so these decorations normally don't affect the vertical position of images, relatively to the text.

Stopping the text flow[edit]

On occasion it is desirable to stop text (or other inline non-floating images) from flowing around a floating image. Depending on the web browser's screen resolution and such, text flow on the right side of an image may cause a section header (for instance, == My Header ==) to appear to the right of the image, instead of below it, as a user may expect. The text flow can be stopped by placing {{clear|all}} (or if you prefer, {{clear}}) before the text that should start below the floating image. (This may also be done without an empty line by wrapping the section with the floating images with <div style="overflow: hidden">…</div>, which clears all floats inside the div element.)

All images rendered as blocks (including non-floating centered images, left- or right-floating images, as well as framed or thumbnailed floating images) are implicitly breaking the surrounding lines of text (terminating the current block of text before the image, and creating a new paragraph for the text after them). They will then stack vertically along their left or right alignment margin (or along the center line between these margins for centered images).

Altering the default link target[edit]

The following table shows how to alter the link target (whose default is the image description page) or how to remove it. Changing the link does not alter the format described in the previous sections.

Description You type You get
internal link ... text text text [[File:Example image.png|link=Main Page|caption]] text text text ... ... text text text caption text text text ...
external link ... text text text [[File:Example image.png|link=http://help.gamepedia.com/Gamepedia_Help_Wiki|caption]] text text text ... ... text text text caption text text text ...
no link (external or file page) ... text text text [[File:Example image.png|link=|caption]] text text text ... ... text text text caption text text text ...


WARNING:
C2.png ♦ The licencing requirements on your wiki may not allow you to remove all links to the description page that displays the required authors attributions, the copyrights statements, the applicable licencing terms, or a more complete description of the rendered image (including its history of modifications).

♦ If you change or remove the target link of an image, you will then have to provide somewhere else on your page an explicit link to this description page, or to display the copyright and author statement and a link to the applicable licence, if they are different from the elements applicable to the embedding page itself.

♦ Your wiki policy may restrict the use of the alternate link parameter, or may even enforce a prohibition of alternate link parameters for embedded media files (in which case, the link parameter will be ignored), or may only accept them after validation by authorized users or administrators.

Rendering a gallery of images[edit]

Gallery syntax[edit]

It's easy to make a gallery of thumbnails with the <gallery> tag. The syntax is:

<gallery>
File:file_name.ext|caption|alt=alt language
File:file_name.ext|caption|alt=alt language
{...}
</gallery>

Note that the image code is not enclosed in brackets when enclosed in gallery tags.

Captions are optional, and may contain wiki links or other formatting.

If an image is in the File namespace, the File: prefix can be omitted.

for example:

<gallery>
File:Hydra intro.png|Item 1
File:Hydra intro.png|a link to [[Contents]]
File:Hydra intro.png
File:Hydra intro.png|alt=An example image. It has flowers
File:Hydra intro.png| ''italic caption''
File:Hydra intro.png|on page "{{PAGENAME}}"
</gallery>

is formatted as:

Optional gallery attributes[edit]

The gallery tag itself takes several additional parameters, specified as attribute name-value pairs:

<gallery {parameters}>
{images}
</gallery>
  • caption="{caption}": (caption text between double quotes for more than a word) sets a caption centered atop the gallery.
  • widths={width}px: sets the widths of the images, default 120px. Note the plural, widths
  • heights={heights}px: sets the (max) heights of the images.
  • perrow={integer}: sets the number of images per row.
  • showfilename={anything}: Show the filenames of the images in the individual captions for each image (1.17+)

Example code:

<gallery widths=60px heights=60px perrow=7 caption="Hydra likes to party!">
File:Hydra party.png
File:Hydra party.png
File:Hydra party.png
File:Hydra party.png
File:Hydra party.png
</gallery>

Result:

Link behavior[edit]

By default an image links to its file description page. The "link=" option modifies this behavior to link to another page or website, or to turn off the image's linking behavior. Alternatively, you can create a text link to an image's description page or to the image itself.

Text link to image's file description page[edit]

Use a colon (:) before File: to link to image's file description page:

File:Hydra intro.png

[[:File:Hydra intro.png]]

Gamepedia

[[:File:Hydra intro.png|Gamepedia]]

Text link to actual image[edit]

Use pseudo-namespace “Media” for a text link to the actual image:

Media:Hydra intro.png

[[Media:Hydra intro.png]]

Gamepedia

[[Media:Hydra intro.png|Gamepedia]]

(If above gets you instead a text link to the image's file description, not a link to the actual image, perhaps your wiki's namespaces are configured out of compliance with this feature?)


Display image, link it to another page or website[edit]

Use "link=" option to link image to another page or website:

Clicking on the below image will take you to MediaWiki:

[[File:Wiki.png|50px|link=MediaWiki]]

Wiki.png

Clicking on the below image will take you to example.com:

[[File:Wiki.png|50px|link=http://example.com]]

Wiki.png

Display image, turn off link[edit]

Use "link=" option with no value assigned to turn link off entirely; the below image is not a link:

[[File:Wiki.png|50px|link=]]

Wiki.png

Requisites[edit]

Before using images in your page, the system administrator of your wiki must have enabled file uploads and a user has to upload the file. System administrators may also set the wiki to accept files from foreign repositories}}, such as the Wikimedia Commons. For server side image resizing it is necessary to have a scaler configured (such as GD2, ImageMagick, etc.).

Files at other websites[edit]

You can link to an external file available online using the same syntax used for linking to an external web page. With these syntaxes, the image will not be rendered, but only the text of the link to this image will be displayed.

[http://url.for/some/image.png]

Or with a different displayed text:

[http://url.for/some/image.png link text here]

Additional MediaWiki markup or HTML/CSS formatting (for inline elements) is permitted in this displayed text (with the exception of embedded links that would break the surrounding link):

[http://www.example.com/some/image.png Example '''<del>rich</del>''' ''<ins>link text</ins>'' here.]

which renders as: Example rich link text here.

If it is enabled on your wiki, you can also embed external images. To do that, simply insert the image's url:

http://url.for/some/image.png

Currently, embedded images cannot be resized, but they may be formatted by surrounding MediaWiki markup or HTML/CSS code.

If this wiki option is not enabled, the image will not be embedded but rendered as a textual link to the external site, just like above.

Hydra party.png

Yay! You've made it to the end of the page!
