Preloading images?
HI,
I've just read the tutorial on pre loading images with the use of a javascript in the <HEAD>. I was wondering does the same apply for background images (wallpaper). If so do I need to change the javascript.
Thanks in Advance

You could use the background image in the scritp like you would any other image, though I don't think you can change the background image (ie a rollover etc.) with a script. Preloading shouldn't be a problem though-- but it might not make much difference with a background image since it is only used in one spot.

Ok thats great. Thanks for the help.
The site is www.i-t-f.co.uk (gaming web site)
and sometimes the background takes a little bit to load, its not really a problem.
Thanks again for your reply.

Pardon my ignorance:
What is the advantage(s) of preloading an image? It seems to me the time to load an image is the same whether it's loaded via the JavaScript preload function or loaded directly into a page. IOW, if I have a 30k image file, will it load faster as a preload than as a URL in the <img> tag?

It doesn't change the loading time of the image, but it starts loading the image before the rest of the page.
It is mainly used for rollovers, where you want the image to change right away rather than waiting on it to download when you mouseover.
