This extension adds 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.

Synopsis

Article with gallery tag

<picLensLauncher>My launch text</picLensLauncher>

… which will display such HTML content :

<a href="#" onclick="javascript:PicLensLite.start();" class="picLensLauncher" title="PicLensLite">My launch text</a>

JavaScript object PicLensLite is maid available by an head script also automatically provided by this extension.

With generated html attribute class="picLensLauncher" you can customize this link with some CSS selector.

Other article

If you can to add a Media RSS to an article that does not use any gallery, you can do it with the special comment <!-- PicLensRSS: url -->.

You just have to replace url by an absolute (<!-- PicLensRSS: http://www.mysite.com/photo.rss -->) or by another wiki article that contains <gallery /> tag(s) (<!-- PicLensRSS: OtherArticleWithGallery -->).

Patches

The default code will not include gallery images without a description in the generated RSS feed used to display the images. To do so, change the following code in PicLens.body.php:

        foreach ($parts as $p) {
          $pos = strpos($p, '|');
#change starts here
          # If it doesn't have a description, use the image title
          if ($pos === false)
          {
            $it = $p;
            $descr = substr($p, strpos($p, ':')+1);
          }
          else
          {
            $it = trim( substr($p, 0, $pos) );
            $descr = trim( substr($p, $pos+1) );
          }
#change ends here
          $title = Title::newFromText($it);
          $img = wfFindFile( $title, false );
