I've pretty much gotten my zenfolio gallery set up the way I want it. I've finally ditched the old gallery and pointed my domain to the new zenfolio account.
Let me tell you, that is a smoooooth and seamless setup. For $100 a year plus a per-order service fee, you get a gallery site with a built in shopping cart and credit card processing. Customers can even customize their prints with mounting and framing, and its all priced out for them according to a pricing formula you set. The best thing is that there's an option to remove all logos and advertising references to zenfolio or the printing house from your web gallery, making it look 100% like your product.
Pretty cool. I'm pretty happy with it. I just need to do a little tweeking of the products and pricing lists, and I'm 100% up and running.
