I was stumped by that, too. Then I discovered the original name I had assigned the image was tucked away in the upper left-hand corner of the image info bar. Look closely, you will find it! I also discovered, through trial-and-error, that image titles with non-descript letters and numbers are duplicates. (I am, however, very new on Auctiva -- so I could be mistaken.)
I keep my inventory by letter-number code, with the exception of Books/LPs/CDs. Shapes, like my Charming Tails and Cherished Teddies are easy to identify in thumbnails. Books/LPs/CDs aren't.
One Newbie to another..
