GuMax-5-0-0 and MediaWiki 1.22.1 - page-Default.gif

[JosefNoll]

Having upgraded to Mediawiki 1.22.1 and GuMax-5-0-0 the images on the respective pages are not found.

e.g. my page: "Research_Areas" should display a banner page-Research_Areas.jpg, but always reverts to page-Default.gif

I ensured that the respective image page-Research_Areas.jpg are in the skins/gumax/images/pages, but it looks like that the path to those images has changed in Mediawiki 1.22.1 and could not be found.
Any idea or update? I use "nice URL" with http://cwi.unik.no/wiki/Research_Areas
Thanks for your help and update
Josef
