don't get me wrong. I was not saying it worth only $20. All I was trying to do was to suggest him to give ebay a try. Some photos sold for $20 on ebay does not mean GangW's photo will be worth $20 only. I have no clue how much his work will be worth for. One way to find out is to put them on ebay, have people bit for it. That will pretty much tell how much they worth from a consumer's point of view.
Besides, $20 USD is not a bad deal, consider you are not selling your copyright. you can always sell more copies, if I am not mistaking.
