Take a look at Mind's Island. They are about to add a host of new features including blogs, postings, paypal and they have an eBay store. In a couple of months there will be a whole new look as well.It's very affordable, and when they update you will be getting a lot more for your money.
It is a good idea to open your own wed site, try Sitesell. It is a Canadian outfit with good product. Then you can put links to those other sites and they will pay you.
Let me second mindsisland. they are based in Mass. and have reasonable rates. you can have as few as 6 images posted and up to 50 stored in an online "warehouse." matter of fact, you can see my work at www.mindsisland.com/members/bundock I am about to reshuffle some images and put in new stuff. Please, have a peek. Bruce
Hi Philip, I just signed up last weekto mindsisland which is now Artid. Its very user friendly and very attractive. I haven't sold anything yet but I have had visitors already. For the price I can't complain. Like they say about the lottery you can win if you don't play, so get your stuff out there http://www.mindsisland.com/members/cldmonet
