Have you considered using PerlScript in your ASP?

<% @LANGUAGE = PerlScript %> 
<% 
      # Embed your Perl right into your page ...

    use Image::IPTCInfo;

    chdir('demo_images');

    # ...

      # ... or if it needs to live seperately, 
      # capture it's output and redirect it to 
      # the browser.

      # This might be redundant: does STDOUT in
      # ASP go to the browser anyway?

    open XML, "-|"
      or exec "/path/to/your/script.pl"
      or die  "Can't exec script.pl: $!\n";

    $Response->Write($_) while <XML>;
%>

If not, then ASPFAQ.com or one of the other ASP sites might be a better place to ask/look.
