    IE (any version) does not support PNG-24 (24-bit PNG files gives you 
that Alpha channel, which allows for transparency.)  It's a known fact 
that IE completely screws with the Alpha channel, and thus will render 
some color in the parts that are supposed to be transparent.  The "fix" 
that Microsoft offers is by tapping into the AlphaImageLoader() routine 
to get proper opacity on PNG files.

    A List Apart has a really good guide on this:

    And Microsoft's MSDN page:
