My stuff is pretty much one of a kind but I keep the saved listings as template for similar or same brand items.
I have been cleaning out my images folders but it is slow and tedious and the stuff I have not listed yet but photographed and uploaded for later listing was cleared by the wizard. Thats stuff I need and it will be hard to go back and find it on my multiple machines and hard drives.
I don't have time to restore as the deleted pics are page by page restore and right now I think I have over 300 pages of deleted items. I tried to find a few when I was listing today and its pretty much the old needle in the haystack thing and there is simply no easy way to navigate the deleted area.
