When using the code in my own page, I found
that I could not get the page to validate at
validator.w3.org, apparently due to the
illegal use of a NAME attribute in an IMG tag. The same goes for your demo page at
http://irt.org/articles/js066/example.htm
despite you having a HTML 4.0 Transitional
DTD stuck on it. I have had no success in
attempting to use the (legal) ID attribute
instead. Any ideas? Thanks, Steven Gibbs

Fine article! Now I'm using this approach myself.

Unfortunately the Javascript code in the article contains a minor typo. In the function imageLoad the image variable names contains an underscore which shouldn't be there. The working example is correct though.

Thank You for a high quality information site. I've learnt alot especially Javascript through irt.org

I used the concepts in this article to help me improve the performance of my page download time. It drastically reduced the time it took.

My images are slightly bloated and need to be thinned out. But this script made it seem as if they weren't bloated at all.

This script was a perfect solution and it also helped me learn some other concepts JavaScript uses.

Right now, although publically available, my work is mostly a testbed to help me further grasp technological concepts. I look forward to the day when I can be a contributer.

Thanks again.

I'm having a problem with my onmouseover & off - even though the images are preloaded, every time I roll over and off, the images are downloaded again.
As an experiment, I took your example page and replaced it with my own images. Result - the example page on your site works fine, but mine causes the images to download every time.
What is wrong? I'm going crazy trying to work this out ... Please help!!
The page with the images replaced, on my site, is:
www.1-art-1.com/mousover.html
Please take a look at this and give me advice.
Help!
