The site I made has a lot of graphics, all where optimized to the internet yet there is still... a lot of graphics.

I notice some sites though have cookie scripts where all the graphics will be stored in the users temp file so it will be easier to download in later hits.

I dare not use other sites cookies by view source. There Javascript is not foramted so well and some of them use ASP, JSP or other scripting technologies drived off their server.

Graphics aren't cached by a cookie, they're cached by the browser.

So scripting wouldnt help eh? My guess will be vbscript, but I hate that stuff.

The best you could do would be to preload the images, but that usually ends up being annoying and more trouble than it's worth.
