While Sitekreator offers good gallery features suitable for artists' websites, their template collection for the free package is rather boring. They have only a couple of templates that I found were stale. I then opted for the blank template and did the entire thing myself.
Have a look at my portfolio and let me know your comments, suggestions, critiques or just about anything else.
Among other things, I have made prints of paintings available through Redbubble also. I think some of you would have noticed already that my sidebar contains a link to my Redbubble profile. Since I came across more positive review for Redbubble as compared to Imagekind, I am giving it a trial. Currently, prints are available through my galleries in ImageKind and Redbubble, and I might switch over to only one a while later.
