Digital Photography ForumFocuses on digital photography from a web development standpoint, such as tips for better product photography, lighting, optimizing photographs for web use, best digital camera choices, etc. Additionally, we encourage you to show off your personal shots!
You could do something like what freedigitalphotos does. Offer a low res version of your photos for free so that you get traffic going. Get adsense going on your site so that you earn from the traffic. Offer high res versions as paid & get what your photos are worth.
Vaguar has the best suggestion to make money. Give the visitor a taste of an image but if they want the finalized version they need to pay a fee or pay for a membership fee. Or to download a photo, the visitor has to pay $1. The more downloads the more money you make plus use adsense or sell ad blocks.
