Recycler renames the files to something silly when it is cleared out, so you may have to search on date/time. I can't remember if it renames the file type as well, possibly it does, so searching for jpg won't find them. Recuva is excellent as it gives you a preview so you can flick through many files quickly.
The bad news is that every time you touch Windows, run programs, etc you're overwriting what's been deleted, so be cautious. Don't reboot, don't post to this forum, don't do anything else if you can help it (even better if you have another pc to use), download Recuva to a flash drive, install it on, and run it from, that. You get the idea.
