That's the idea; the reference to IE "not supporting PNG" is that IE
doesn't support PNG files *as icons* (i.e. in favicon.ico).
This may be a result of IE ignoring the HTTP content-type field and
relying on the "extension" instead (thus assuming the PNG file is in ICO
format) - ISTR by default the browser uses /favicon.ico from that site as
the icon? Using an explicit LINK tag to, say, icon.png may overcome this:
anyone tried it? (I don't have a Windows machine handy...)
