No offense meant, but either you are wrong or we have a problem
understanding each other.  Yes, IE does not support PNG alpha channel.
But if you only need full transparency (the equivalent of what you get
with GIF), you can achieve that with PNG8 in indexed mode (see attached 
PNG).  It work in IE.

It's a common fallacy to believe that transparency == alpha channel;
they are two different (albeit somewhat related) things.  But maybe you
really need an alpha channel to make your image only partially 
translucent, which indexed mode does not provide.
