I honestly can't believe ebay has done nothing. They took the one's down I reported that stole pictures within hours. And the one's that stole my description ebay emailed and said their accounts would be limited. I know this because I got a nasty gram from one saying I should of emailed them first before reporting it to ebay. But at that point I had had it and I shouldn't have to email anyone for stealing my stuff.
Just a quick qustion though do you have it marked in your ebay selling manager not to share pictures? If this is not checked your pictures will go into a catalog that ebay provides for lazy sellers basically and they can use them.
