Dynamically loaded images?

i know there’s a section for this on kirupa.com, but i really need everything spelled out for me. (for instance, i knew the i had to use the code, but i didn’t know where i was supposed to put it).

basically, i’d like to have a loaded image like the splash page on www.heftyrecords.com, where it says “loading images…” and then the images show up. i don’t want to have to click on a button to load the image; rather, i’d like it to be done automatically. could anyone possibly help further explain this to me? :cowboy:
