There’s a foul worm in IE7 that when you’ve installed Apple Quicktime, Itunes or any other third party instrument on home windows Vista IE7 is unable to open .png .jpeg or .jpg information if immediately linked to them. IE7 appears to supply it as an Apple Quicktime object. the quick restoration for this is to both disable UAC (person Account control) on Vista or run IE7 as an administrator. it appears also a full structure and reinstalling Vista works.
