I use ebay's prelist information (provides tracklists, etc) on the cd/dvd/game, but try and include my own pic too. Ebay has a lot of frauds trying to sell bogus shit on there, so I want my bidder to see that I took the time to get my own pic, especially on really rare stuff. If it is just common shit, I doubt it matters too much. That is just my own preference though.
