Fixing Phark for IE5/Win

Phark is the name of a common image replacement method that only web geeks care anything about. It's clean and smart, but it fails in Internet Explorer 5.0 for Windows.

Or rather, it used to. Or rather, it still does, but there is now a simple and easy way to keep using Phark and having image replacement work in IE5 as well. I've documented the trick here, but if you have any comments, please attach them to this thread.

I haven't seen this particular workaround documented anywhere else, but if I'm not crediting the right people, please let me know and apologies all around.
