I had been looking for a way for people to buy some of my best photographs, which is one of the reasons I ended up on this host for my website. I'll eventually be able to sell digital content here and the host will take care of the encryption, passwords, payment, and all those important but difficult to manage details.
In the meantime, I set up account on Imagekind, which will allow people to purchase regular and canvas prints, with or without frames and matting, of the photos I've made available. I've been uploading large-format images and now have over a hundred available. Here's the link: http://HuberJack.imagekind.com/
Don't forget to let me know you bought something and/or what you think of some of my work...
