You still click on the tab where you could edit (before someone bids). It's to the right of where you have the option to make it a Premium Listing. Just click on the button to update. It just says you can't override your original posting, but you can add photos.
that option isn't highlighted so I can click on it. :( sorry guys I wanted to show the clips I would give once I reached 400 . which I did thank you bidders. i will be posting need clips after this auction is over.
