I downloaded a cover for an ebook that didn't have one. Worked fine. BUT
when I downloaded another, there was a pop up window which asked about the network allowed. There was an ALL option, a PUBLIC option and something in the middle, maybe PRIVATE? and a box for always. Well, I went ahead and made a selection but I guess I wasn't paying attention and must have clicked the wrong one as I can't get any covers. Of course, I clicked the always box, so I no longer get the option to choose. Where do I go to undo that selection?

I got there with:
Edit Metadata ==> individual metadata ==> download covers
