I have been doing the Amazon to eBay arbitrage game for a little while now. And the other day I got a notification that one of my auctions was removed because the photos I used were copyrighted. I've heard people say they use software to crop these photos and rename them to get around this. What kind of software are you using to accomplish this? Is cropping, renaming and adding a watermark enough to get around this? Should I add a border or something? What are some tactics you use? Is there hidden metadata that needs to be removed? Thanks in advance.
