Ken,

I'm not aware of anyone doing anything quite like this.  gdalinfo isn't
setup to be used as a cgi, and doesn't return things html encoded or
with a content-type header.  And MapServer does not have an equivelent
functionality.

But, in theory, you could write a little gdalinfo script in php/perl/python
that would execute gdalinfo on a passed argument filename and then return
the result with a proper "Content-type: text/plain" header.

Best regards,
