If I had guns or religion, I’d cling to them because of this browser. I would shoot it in the face and pray to god that my bullets obliterate this heathen.

So here it is, for my consideration and yours, the bare minimum for a flicker-less image swap hover for IE6.

First, ALWAYS set your doc type to strict!

<style type="text/css">
	a { display:block; }
	a:hover { background-color:#FFF; }
	/* YOU MUST HAVE A BACKGROUND COLOR HERE. */

	a img { height:0; width:0; }
	a:hover img { height:50px; width:50px; }
</style>

<a>text or image<img src="image.gif"></a>

I was about to shatter a cd and shove the best shiv into my eye socket because of this.
