I'm trying to upload photos originally saved off XP onto a cd and now wish to upload them onto Windows 7.

But, when trying to do so the computer recognises the files currently on the disc but when I try to open them the following appears:

Photo Gallery can't open this photo or video.  This file is not supported or you don't have the latest updates to Photo Gallery.

I'm not very good with computers, as you may have guessed, but could you please advise how I can rectify the situation.  Thanks in anticipation.
