How do I restore photos in Media Center in Windows XP Dell?

I have a Dell XPS 400 Windows XP with a 13 in 1 Media reader, which I started in May 2006. I put my digital camera card into the reader and downloaded some pictures of some 2 mo August Since then, I downloaded a bunch more pictures and decided to start burning them CD. While I downloaded all the recent photos, I seemed to lose the photos a few months ago. I had not canceled my card fromt the recent photos, but when Media Reader to read the card, he has the photos that I lost a file that can not access. Says there is no valid images in this file. They are not the card from the camera as well. Is there a way to restore them so I can burn them to a CD? I tried to restore my system, but was not successful in restoring lost photos. Can anyone help? I'm obsessed with trying to recover them, as they are, once in a lifetime pics. Any information would be greatly appreciated! Thanks a lot!

Need a little more information. Im not clear where you think the photos are. Lost in a file? Files are usually photos stored in a folder and not one unless your file as a zip file or somthing. You could try to handle Picassa photo software from Google. Install it. Then, have to scan the computer for photos hole. Should find them if there on your computer. GL
