I have also been thinking of doing something like this. I don't know if you have ever done any Wordpress themes, but they aren't too tough. I went through this tutorial - http://www.wpdesigner.com/2007/02/19...ss-themes-huh/ and have now done a few themes to match client sites. Here is the one from my web design web site: http://www.macgroveweb.com/blog
I have not really done much with images, however, so that is next for me.
So, I guess I don't have a heck of a lot to offer, but just that I agree that it seems like a good idea.
