I'm also an artist on the side, so get some traffic to my business site from people tracking me down about artwork.
My oldest gallery is on VCL which has stuff all the back to 2000! It is confined to furry art however.
http://us.vclart.net/vcl/Artists/Fenris-Lorsrai/Conveniently, it also has some of the paintings I've done of the shop window, including this run showing the process of painting the window. (note the huge website address in final image. We no longer have it painted on window like that)
http://us.vclart.net/vcl/Artists/Fenris-Lorsrai/Sketches/glasspainting/index01-by-date.htmlFor more thorough archives, I point people at the Deviantart site. it only goes back to 2004, but includes a lot of sketches and normal artwork:

VCL doesn't allow comments, but does allow you to link your VCL art to the same art on FA, so I get it doubled up traffic from VCL browsers leaving comments on FA:

http://www.flickr.com/photos/21881149@N06/haven't gotten any bites so far on Flick, but I've only joined two groups thusfar.
(I do have two more galleries, but I almost never use due to ongoing technical issues with the hosts and INTERNET DRAMA! OH NOES! They're too much effort to keep on top of. If I get anything from 'em, great! But I've largely let them go fallow cause they drive me nuts. I also have a Myspace page, which I almost never update because I hate being attacked by random blinking ads)
Some of those may be useful to other arty types.
