Also, try thinking sideways at the problem. Here in the UK there are on-line services which do photographic printing of digital images, meant for digital photos. but there's no reason not to use them for CGI images. It may be a good answer for a set of sample images, or if you want a physical album to show people. This doesn't compete with the CafePress style of operation, but if somebody local wanted a physical copy of one of my images it looks a better deal. (The service I have an account can be found via my ISP's web page, www.tiscali.co.uk)
