Yes, don't give up. You will find a way here, even if you need to scrap tips & tricks somehow. Although having said that, I don't customize here a lot either *lol*
I've got one of my books with the wrong cover and a handful missing altogether. The missing ones I'll live with for now - but what the heck do i do with a wrong cover? Pfft. *grumbles with Jenn
You can edit the post, and linked it with the right book and the right cover. I got one wrong one for ZAM My Cowboy Heart. I edited it and searched for the book with the right cover. Linked to that book and deleted the wrong one
Casey. Go into your blog (not your shelf). Scroll down until you find the review with the cover that's wrong. Click the edit button, then click the picture up in the top box that's wrong, then click the add button and search for the correct book. Then save it.
It takes a lot of getting used to! I've been messing out with it for about a week and am just getting to grips with it now. Chin up, it'll all come together :D
