Something rather pointless which I figured out...

After a couple hours of trouble trying to preload images with JavaScript, I figured out that I can do the same thing just by including the images with no display:

<img src="whatever" style="display:none" />

So I guess that's a good way to preload images for people with JavaScript disabled, not that there's that many.

You can generate the preload images javascript code here for free.

The <img src="whatever" style="display:none" /> will just take up space and SE's may frown on it (hidden images) but this is a guess.

Oh, no it's not that... I know how to preload images... I just have a comlex app with spaghetti code and include files and it was that stuff that was making it a headache to preload with javascript. So I just figured out a way that worked in my specific situation.
