Hi Mary, I believe that when you make your new Shiny Tree( KEEP THAT OLD TREE that you have just made a mistake)
You can now then upload the New SHINY TREE to overwrite the OLD one and you should find your Photographs are there.
Just to check ARE THEY STILL THERE in the one you just made a mistake on. If so this will prove me correct
Anxious to know
Regards
Les
