I must have been living in a cave, but I just discovered that you can link you blog to your flickr account, and upload images with a post directly to your website.
Since a load of peole he have websites and want to display art, this might be very useful. Create a free account, upload you artwork (and categorise it to a certain extent), then link it to your site. If you are running your site with an underlying blog technology like blogspot, worpress, moveabletype etc, you can then upload your image to Flickr and have it appear on your news page.

Oh, and the spellchecking in these edit boxes with Firefox 2 beta is grand.
