Images: Testing, Research

Despite numerous cultural prohibitions regarding image worship and idolatry, images are still useful elements to include in wiki articles.

• Manual:Image Administration

This article describes how MediaWiki handles and stores files, and gives some information on configuring.

• Manual:$wgAllowImageTag

Allow <img> tag to be used in wikitext. Introduced in version: 1.17.0 (r65286).

Gallery

Moved images formerly occupying this space to User:WikiMaster/Gallery#Sofia.

Gallery Resources

• Category:Image gallery extensions

The Image gallery extensions category contains articles on extensions that embed a collection of images (a gallery) in a MediaWiki article.

• User:Makthorpe/gallery xfer1

A nice simple gallery example.

• Extension:User Image Gallery

The User Image Gallery extension introduces a <userimages> tag to the MediaWiki markup, which can be used to produce an image gallery of all recent uploads by a particular user, up to a specified limit.

• Extension:PicLens

This extension adds Media RSS support to Mediawiki's standard <gallery /> tag. This allows it to generate Media RSS content from any article that contains such tags. It allows you to add a RSS Media link to any article that does not have gallery with a special comment. It also allows the PicLens plugin to be used with such RSS with another particular tag.

Linked Images

• Manual:Linked images
• (Link to MediaWiki sunflower logo.)

Images on a MediaWiki wiki will by default, link to the description page. However, there are several workarounds for those that require them.

Example

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

(Links sunflower from commons.wikimedia.org to MediaWiki's main page.)

Linking to External Images

How-To-Do-It Source

• Manual:Linked images | Native with configuration change | External image syntax
• Manual:$wgAllowExternalImages (Currently set to false on PortlandWiki.) --17:09, 25 September 2011 (PDT)

When set to true, users can bring in an inline image from an external URL. They do this simply by sticking the full URL into the wiki text (without any other surrounding markup) That is the direct URL to an image resource on another website.

When set to false, the full URL appears as a text link to the image.

Note that if you want to allow images from a single trusted source (e.g. from within your own domain) then set this to false, and use $wgAllowExternalImagesFrom.

• Manual:$wgAllowExternalImages (Currently set to true on PortlandWiki.) --17:09, 25 September 2011 (PDT)

If $wgAllowExternalImages is false, you can specify an exception here. Image URLs that start with this string are then rendered, while all others are not. You can use this to set up a trusted, simple repository of images. As of r40310 (1.14.0), this may be an array of strings.

1. Make appropriate changes to LocalSettings.php. Example

$wgAllowExternalImagesFrom = array(
'http://www.ussf2010.org/',
'http://ussf2010.org/',
);

2. Insert wiki markup code. Example

<span class="plainlinks">[http://www.ussf2010.org/ http://ussf2010.org/sites/default/themes/ussf-2010-theme/images/USSocial-Forum.gif]</span>

Image Linking Extensions

• Extension:ImageLink

Creates a clickable image link using an image in an article and an article title. This image can be either stored in the Image namespace or accessible through an interwiki prefix. The article title may or may not exist in the database.

Extension:ImageLink is needed for MediaWiki installations until version 1.13.x. Since MediaWiki version 1.14+, a parameter "link=" can be added to any image, without the need to install an extension. But only basic functionality of this extension was integrated into MediaWiki software 1.14+. Some HTML attributes and all of the event attributes are still not part of the MediaWiki software.

• Extension:EmbedImg (Installed on PortlandWiki.)

The EmbedImg extension adds the <img> tag for embedding external images. It supports width & height parameters.
