Recovery of JPEG (from digital camera) photos.

I had the photos on Windows (Vista) Photo Gallery and wanted to transfer them to Picasa 3. I was able to do this with other sets, but with this set only 2 or 3 showed up. Ordinary searches for the folder fail..."Folder is empty". I ran a scan with Recuva and found what I think may be them, and they are designated excellent and recoverable. My attempts to open the files get me a black box that says

"Invalid Image". I need help in finding what I'm doing wrong. Thanks.
