I usually change them without problem, but I'm trying with that one: https://www.bookcrossing.com/---/14605223 , it says "the image was updated", but it is not. I tried to upload different pictures and it's always the same, so the problem is not the image. I have the same problem with another book, does anyone know if it is a bug happening now?
Cute puppies in the image I can see! I gather that was a duplicate-registration that you want to re-use at some point; if you have new book-information to enter, try doing that before you update the cover image and see if that helps.
I have noticed that attempts to change an existing photo sometimes seem to fail, only to kick in hours (and hours and hours) later; not sure if that's the same situation here or not.
Really? Well that's not the picture I intended to upload, but must be one of the ones I tried afterwards to see if the picture was the problem! And I still see the same wrong cover, not the puppies one, how is it possible I don't see the same as you?
Well, I'm trying now to upload the cover of a book that I have not registered yet, and will check later if it appears!
