Ok, here's how we do it! Just bring this up in the header section of your page...
This script will sniff out all your images and making it preloaded to your page -- you'll notice that your page loads a bit faster than the usual one...
shrink the image first, many people will not wait.
as long as there is a size set for the image, fake it
create a 1pixel square image and load that into the 800*600(example) image space.
If the image is being preloaded for a subsequent page, its easier
on a previous page will put the image in TIF ready for a call
