Hmmm, I think it is the file, but to be sure.
Is it possible to send me one of the pictures to see if the same happens on my PC?
Attach the pic and then I will save it and see if I can open in Vista and if it has the same effect?
If it does, it is the files, if it doesn't, its the settings on your machine, and we will have something to work on?
Cheers
Jamie
