5. My Name Is My Name
If you are grabbing something from an individual whether it's from eBay or Sole Collector or even Craigslist, have them throw their name in the photo so you know the photographs show the actual sneaker you're being sold, and that they are actually in the seller's possession.

And it should be a handwritten tag, not just a Photoshop job. But you knew that.
