Mine is through SM. I have only used options available from them, and no very little about programming code, etc.
I like that my portrait clients can review and buy from their password protected galleries. That saves me time, but some will say it lowers your average sale as you are not there to help realize how important a large photo order is.
Mine is a Zenfolio pro business account and I love it! I had Smugmug prior and became tiresome of going to the Dgrin forums to learn how to change things everytime I wanted to do something to my website. Zenfolio is very user friendly.
My site for my commerical photography business: www.arthurdomagala.com
I use aphotofolio, which has been an absolute pleasure and much easier to set up and continually update than coding my own site (which is how I did my first site).
Also, I have a separate site set up for selling art prints: www.domagalaprints.com
The prints site I set up through artspan, which is not quite as slick on the frontend or as easy to use on the backend as aphotofolio. But their customer service is pretty decent.
I redid mine this fall. No flash, all javascript with a little css3 for those that can use it. It has a nice backend where you can easily create/remove categories, upload with an auto resize and placement, delete/reorder photos etc. Images right now are a little big, they also should prob have some watermark, I need to see if its possible to auto add that on the upload. I need to be able to just drag and drop photos into it or it'll never get updated. Let me know what you think.
artd ... diggin it on the commercial site, not as much on the selling site. I like the floating left/right advance and the center filmstrip button. Also diggin' the full size images to get some presence and your work as well is pretty kickin'.
Thanks Rusty, much appreciated. The artspan site is admittedly rather pedestrian (though I keep telling myself when I have the time one day I'll dig into the backend to see how to spruce it up some :P ) But it was more economical than doing a second aphotofolio site and the paypal shopping cart has come in handy at least...
Designed it myself, by trade I am a professional web designer. I work as a project and Technology Manager now but have worked as a professional photographer in the past. Check out the gallery section for some of my past photo work :-)
www.theallenchu.com Another free template.. back to flash. Waiting on an agent i'm signing with to handle new mobile friendly build LoudSpark link on the bottom for link to template.
I built mine from scratch and used Web Builder 8 (link) along with Lightroom 3.6 for the galleries.
Their software will allow you to build up your own galleries including one for hosting and selling using Paypal.
It is one of the best WYSIWYG out there. I was actually apprehensive because of the low price of $45.00 but it has not disappointed me, plus you can try out the free 30-day trial.
