I wasn't aware until now that it wasn't possible to do that. I put a photo on the flap of my book and added text, it looked fine so I sent it off, but I have been trying to edit this flap subsequently to add more information and couldn't find the flap...thanks to you I now know why!!, but as you say, this is very annoying. The only answer I can see is to delete the back cover photograph and put this author information on the back cover instead. A friend of mine has done that with his book and it looks ok, but I am a little cross that I wasn't aware of this before I sent my book to print as there won't be any author information on my book now.
