Under your third reference I do find the themes, but they are DLLs or something similar. These hold the pictures that show up under the category "Desktop Backgrounds" in the Personalization CP.
I'd like to be able to select pictures from those 4 collections as well as from the Pictures Library category, to make my My Theme. The only way I've found to do this would be to collect all the pictures into the Pictures Library location, since it's the one that contains pictures rather than DLLs.
Is there any way to extract the pictures from the Windows Desktop Backgrounds DLLs (.themes) so they can be placed together with the ones in Picture Library?
The property sheet says the file opens with Windows Shell Common DLL?
Thanks so much for your help --
