[PHP] preload dynamic image problems

[Adrian Murphy]

This seems strange to me but i promise it's happening.
I'm dynamically creating images for a page ,calling them so:
<img src="butonn.php?string=hello">
I'm also preloading the mouseover versions.
the problem is that the images are not being preloaded:
javascript problem you say?
the strange thing is that when i use the source of the php
page and save it as a html page,the html page works fine!
I've encountered a few strange problems with image generation stuff.any ideas
