Preloading, xml, musings

OKAY, I’ve been doing a lot of portfolio work (ie lots of photos) and just started incorperating xml databases. So this is new, but am very happy with the results so far.

MY general question is, how does http://www.group94.com (who does a lot of sites for photographers, and are really good designers) get such efficient load times on images. Go to pretty much any one of their sites and there is like, no delay for some very high quality jpg files of substantial size. At first I thought they somehow preloaded everything, or a lot, but well, things happen fast.

Also, looking for any external musings on the subjects of 1. PRELOADING 2. XML databases

THAT’s it…
