If you absolutely must do this, find some legit seller photos of the items in question, and remove their watermarks/markings in photoshop or crop them. You could try google image search and ioffer for this. Don't re-use other people's photos from ebay, that's just asking for it. If ebay/pp contacts you asking where you got the stuff, say at auction, download some receipt software and print a receipt for the items. Use a legit auctionhouse that is not very popular. Sell item, hope you don't get reverse charged. Surprisingly, 2 out of 3 times, as long as the item is of good quality, you won't get any complaints.
