Ah. I didn't catch the naming of the Photo widgets. Thank you.
Yes, this was just a proof of problem code, so I removed as much as I could, and just put in the button part so that I could see a "before and after" of trying to set Image-B.
Thank you again for the naming tip. I didn't realize the given name had such significance.
