Thread:Project:Support desk/Generate Thumbnails via thumbs.php

Hi, i need generate automaticly thumbnails with a width of 140 pixel width for my Extension:RSSpublisher.

With the images that i upload direct to my Mediawiki instance, it works with a URL like http://thwiki.org/thumb.php?f=2003_escort_150px.jpg&w=140

But the most images from my MediaWiki instance, are stored on the Mediawiki commons. When i use the same way of URL like http://thwiki.org/thumb.php?f=THW_Eisemann_13kva_Stromerzeuger.jpg&w=140, i get the message "The source file 'THW_Eisemann_13kva_Stromerzeuger.jpg' does not exist."

How can i generate thumbnails in a customized size ?
