I am happily editing/photoshopping photos in PS CS6 before saving them as jpgs & copying these into an active folder to upload. All tiny picture icons are visible above the file names…. until suddenly the new ones I am working on appear minus their icons. There is a blank above their filenames. I can't see what's what until I open them. They open fine. They are jpg. I have done nothing different with these. The ones I had saved earlier still have their icons. I have quit PS & restarted. Nothing changed: I still have missing icons on these latest files. How do I get all these icons back for my newest photos? Please help! I can't see what I'm doing!
