You could try something like Website Builder for Website Building - Moonfruit SiteMaker to build the website then set up a seperate link to a ecommerce site built through Domain name registration from 123-reg where you can pay for the webname as the same time. Both cover hosting as part of the costs.

I've gone down this route. I liked the look of the ones above but my only issue was when you go to buy something and you have to start emailing people it loses compulsive buyers.

By setting up your own ecommerce section on 123-reg.co.uk whilst it takes a while to set up means you can sell photos there and then, as long as you have your own places you can then get the stock from and send it on.

Hope that ramble made some sense!
