<![endif]-->When reviewing the code, I didn't see any comments about any issues with it being blocked, and the two machines at work I've tested it on previously (most likely default settings) did not complain.
It may affect some user if they've customised the security settings, I guess.
But I say, f**k 'em
Oh, one more thing... change the style to this:
Code:<!--[if lte IE 6]> <style type="text/css" media="screen"> img { behavior: url("/pngbehaviour.htc"); } </style> <![endif]-->
