As you may have read in the Credits or SiteDesigns nodes, the site header is a sort of showcase for my Photo Album.
I used to have over one hundred image previews of all the header images here, but it was hard to maintain and more than a little bandwidth-heavy, so I decided to remove it.
The header will show you 20 different headers, randomly selected for a daily rotation - except on Xmas or other holidays, where the rotation is taken over by themed headers, managed separately.
There are currently over 380 different images of my own making, some of which aren't photos (there are a few commemorative images, some experimental artwork and the random illustration).
