Seeking Salvador question

I'm trying to change the image of my book on Goodreads. I have redone the book covers and in the online stores they are all changed but no on here. When I try to delete the graphic and replace it with the new one, it says that I must have "Librarian" status to do so. I emailed to Goodreads and got no response. How do I change my covers on this website? Thanks for any ideas.
