Well mostly, png are usually a few percent smaller. Png also have full
alpha channels where gif only have one color that may be transparent.
Gif is (up to) 256 (8 bit)colors, png have up to 32 bits (or is that 48 
bits I'm not
sure).

That would be _really_ complex. What about pages that have images as
background. What about the browsers default background (seems to be
mostly white today, but can be changed depending on browser).
What about the user that only watches an image (as opposed to an image
that is part of a web page).

So I do not think that there is much to do about this, provide a link to
the unfiltered page seems to do it for me.

It is not something that I will implement this century anyway.

As for converting images into png files: "convert infile.gif outfile.png"
yes it is that simple.  You could also try something like
"convert infile.jpeg png:outfile.P" if you want any other extension than 
png.

Reading the man page for convert will reveal many more nice
things that it can do.
