I agree about the shape, Doug, and I'm slowly making my way through my galleries adding them one by one. I'm up to about 450 - about 1/6 of what I expect to have eventually. I did have a few pngs on transparent backgrounds that I put up right away, but like Sharon, I found a number of them needed attention. And I have a "square format" gallery so I was able to add most of those in a bulk edit. But otherwise, I'm working through them at the rate of 10-20 per day. I would absolutely NOT be doing this just for the stickers, but there are a number of other things that need to be checked and attended to in edit on most of my images, so I'm doing that "housekeeping" as I go. Haven't sold a one, though :)
The real reason I asked is that after a little spurt of reviews maybe a week to 10 days after they became available, I haven't seen any reviews on them at all.
