eBay care about copyright issues, if you're big enough. A while back my wife had a deal with an artist who specialises in caricatures of celebrities, mainly sportsmen. He's quite well respected, and has photos of himself presenting the caricatures to many of the subjects. The deal was that he would put our t-shirts on his site, and we'd put them on our website and on eBay, and we'd split the difference.
So we bunged a load of t-shirts on eBay, and a load of them were removed for copyright violation. One of the large football shirt companies had objected. Thing is, some of the caricatures were of players from teams that didn't have their shirts.
So money talks on eBay. Powersellers and those with high feedback can get away with murder...
