// This function will check to see if the current browser is IE and, if it is,
//	replace all PNG <img> references with alpha-transparency-enabled versions
//	in-place.
//
// Known bugs:
//	- Does not affect non-<img> images (e.g. backgrounds)
//	- Does not respect altered positioning from borders (i.e. an <img> with a 2-pixel
//		CSS border will still be positioned at the absolute top and left when changed)
//	- No handling of images added after the code is run
