The screenshot shows that Elements can't read your pictures. To 'corrupt' pictures, Elements would have to - 1 - read files, 2 - save files. So, the first thing to check is that your files are correct. That does not mean precisely 'corrupted' or 'sound', that means that they can be read with softwares able to read jpeg format and standard metadata/exif. It's frequent that jpeg files can't be read with Elements or other softwares because they have non standard or really 'corrupt' exif data (mostly with phones photos). If you are using test jpegs to be found as samples on Internet, that should not happen. Many simple jpeg browsers ignore those metadata and are able to open those files and save them in a way that Elements or other serious editors can read. Chances are that you'll be able to recover all your files without the 'corrupt' metadata. To be sure, I can't find any other solution that posting one of the unreadable jpeg files on a site like Dropbox to see if others can confirm the problem.
