Been selling photos on Etsy for a while (or trying to ;-) but finally made the move to accepting Bitcoins - BTC amount quoted on request, but exchange rate seems fairly stable now, which is nice... Have a look here if you're interested:http://www.etsy.com/shop/anothertree
All photos available in small/medium/large, but only listing small size for the moment - each size limited to a set run. Also planning to add more items soon. Photos come mounted but not framed, unless requested - just ask if any questions.
Cheers for looking :)
