I am the first person to recognize that serious, professional artists need serious, professional Web sites. I encourage all of my clients to get their own site with their name in the URL.
Having said that, I know not everyone can afford a site at this very minute. If you’re in this category, at least post some of your images online now with a photo log. My friend, Brian, uses Flickr to show off his collages. I use PhotoWorks for printing my digital images, but I can still send people to my albums.
Having a photo log online is a temporary solution to having no Web site at all. Save up and get your own site. In the meantime, create a small space on the Internet where you can send people to see your work.
Oh, yes, make sure you ALWAYS have the best images available of your art. There are no substitutions for high-quality photographs.
