[Mediawiki-l] Can't view uploaded images

[Vytautas Baciulis]

Hi!
I have problem with my Mediawiki system. I've uploaded PNG and JPG
files, but system just don't show them and writes only "No higher
resolution available.".
Here's URL: http://wiki.infosoft.lt/pages/Special:ListFiles
I checked in cPanel, files weren't corrupted.
The problem is quite similar to written at
http://webservices.blog.gustavus.edu/2007/06/18/fixing-broken-png-uploads-with-mediawiki/
However, PNG and JPG are supported (they are listed in cPanel MIME-TYPE
page) and even MediaWiki shows the mine-type.
What might be wrong?
