Thanks Ben. I'm glad I wasn't totally misunderstanding what the script should do even if I hadn't appreciated what the AutoIt script did. I'll try out the new version.

The images I have without any DTOrg info are almost all ones that have been sent to me by other family members. Some are scanned negatives, others seem to have been edited by PS4 - I don't know if this stripped exif data, certainly it is missing. One or two I edited when I was experimenting with numerous different editors (Lightzone/photofiltre/PictureWindow Pro & others). I suspect one of them - I can't even be sure which now - stripped away exif info.
