Photography website

hi ive been asked to produce a website that is for a visualisation company and therefore the content is almost entirely photos (jpegs or whatever).
It is therefore important that these photos are a decent size and also high quality. What is the best way to produce this without making the website incredibly slow at loading. Importing the images into the fla file is obviuosly a bad idea as the file quickly becomes massive!! In the past i have loaded external swfs into blank MCs but this still isnt ideal or terribly fast ive noticed (and this has been far smaller images). A website that achieves the quality and speed i would like is www.sksantos.com and in an ideal world this is what i would like to achieve. However i am a bit of a novice with AS and therefore would appreciate any help.

thanks anybody.
