Data is persisted through the Value property. What happens if you set that to 
the contents of the dropped file?

It sort of works.
Replaced self.Foto.Picture = filelist[0] with self.Foto.Value = filelist[0]
You replaced the Value with the file path, not the contents. Try this:

self.Foto.Value = open(filelist[0], "rb").read()


Thanks Ed, that almost did it. Now this part works as it should.
The picture persists as I go next and back. But when I exit the form it 
asks me if I want to save changes, answer yes and now I think I hit a 
bug, no decoding should be taking place here as it's binary info :
