I'm using IE 8, so I don't know what to tell you.

Something must have corrupted the JPGs somehow in a way IE doesn't like.
Anyways,
Frantisek, all you have to do is get the file(s) off your FTP, re-save it in Photoshop, or GIMP, or whatever, upload, and it will work again. Since usually there are only a few featured games (makes no sense to have hundreds of them as "featured") then its not a lot of work. You could also do a batch job in Photoshop to convert them all.
hey, here's a test. can you see this in your IE browser?
