>- Does PhotoShop use a private tag for storing thumbnails?

Look for IPTC - NAA (Information Interchange Model/Digital Newsphoto Parameter Record Version 4) I asked for it in a: Comite International del Telecommunications de Presse. I only have a printed version.
I used it to extract caption text of Photoshop Jpg files, and I remember I see the thumbnail tag.
If you dont find that info, I can give you more data.
