Digital Photo Frame, EXIF Thumbnail, Edited Pix

[Perry]

Situation
Thousands of B&W pix being digitised from albums
using an Olympus camera
Pix are reviewed and edited on PC, including cropping
Edited pix are transferred to a camera memory stick
Memory Stick is inserted in ADS Digital Photo Frame [DPF]

Problem
The DPF firmware is displaying the EXIF thumbnail in pre-
view mode, but showing the edited pic in full screen mode.

Desired Solution
Batch updating of EXIF thumbnail so that it matches edited pic.

Possible?
