I am currently using PSE10 so can you try this:
1) Launch PSE10 and go to Organizer;
2) Now go to: File Reconnect >>All Missing Files
This will only work if you have created a catalog of your photos that is accessible in PSE10 on that particular machine.
If you are moving files all the time without moving the catalog then it won't work.
However, I don't know what is "inserting into frame". Do you mean to say that it is some external photo viewer?
Yes. I have saved photos to USB to view on an external Digital picture frame.
Thank you. I will try your suggestion.
