You're probably not going to sell any prints, or not very many, at all. The market is extremely saturated. Possibly it is the most saturated market that has ever been observed in any economy.
Be prepared to do some marketing, if you want to shift any product. If you just want to make prints available to friends, family, and the occasional FOAF or random buyer, there are any number of web sites that will let you set up a gallery, and which will do print-order fulfillment on the backend. As well as mugs, T-shirts, and so on, if you want to offer those for sale too. smugmug.com comes to mind, but there are several others, I think.
