Need help displaying thumbs in FF/IE – F8-Static theme

Hi @ll!

I’ve installed the f8-static theme to use my blog as a pholio, including the galleria plugin, etc. at http://www.strzelecki.de/wp/

If you browse e.g. the ‘open shooting’ gallery (http://www.strzelecki.de/wp/?p=44) the thunbnails are not being displayed in Firefox and Internet Explorer but in Chrome, Safari and Opera. I absolutely have no idea where and what the problem is. Can anyone please help me?

Thanks in advance.

Sebastian
