As some readers (OK, a reader) have asked for it I'm giving away the farm here and letting you all know how to make transparent PNG images display properly in Internet Explorer.

IE 7 won't be along for a while and when it does finally get here it'll still be 5 years before we can stop providing for previous versions of IE anyway so if you're writing a web portfolio or any (X)HTML that needs transparent imagery, you'll need this.
Don't say I never give you anything.
