While stock pictures are allowed in auctions, they should not be the only pictures shown. Listia strongly recommends that you also include pictures of the actual item that is being auctioned. While this isn't a requirement, this is requested so that sellers get higher bids from more bidders, and for the protection of our users who might be interested in bidding on your item. It'll also prevent your auction from getting flagged by multiple users. We don't want your auction to get deleted for seeming like it's not in your possession.
Thanks for your cooperation and good luck with your auction!
