It is a known IE problem.

There is a less-nasty hack.  Use the sRGB colorspace (we probably already
are, if the images look OK on PC's), put an sRGB chunk in the PNG file
but omit the gAMA chunk.  It is the gAMA chunk that IE is mishandling.
I doubt that they will ever fix it because of a 5-year legacy of PNG
files that have been adjusted to look right on IE.
