I put something under Finds, then found a better picture (both Neiman Marcus). I would like to either eliminate the one that is a whole outfit or change the cover photo to just the pants. How can I do this?

Also, having posted a Find, I know I've been able, by trial and error, to post additional photos under it, at least in Custom Finds. I can't seem to go back and do this for my store finds. What am I missing?
