Also, I seem to recall reading somewhere that IE as of the latest version has
BROKEN their support of PNG (I could be mistaken).  The workaround was posted by
MS and involved adding about 100 lines of ActiveX code preceeding each use of
PNG.  Yick!

But maybe it was a rumor, or maybe they resolved it.
