Finding an auction with decent photos is only half the battle. How do you know those photos are actually of the shoe you're bidding on? Handwritten or printed tags are really the only sure way to tell, and are generally the mark of a trustworthy seller (as if the feedback and/or Power Seller rating wasn't enough). If someone has multiple auctions going using the same photos it could just mean they're lazy—or they could be trying to put one over.
