in reply to httpd error_log (perhaps you forgot to load "gd"?)

Besides the missing $'s, you also aren't doing anything with the $gd object you created, you can't simply start drawing and expect that GD will know how to get that image to the web browser. What you will have to do is either have GD save the image you are creating to a file, or have a separate script that draws and outputs the image, but either way you will need to include an <img> tag in the html that you are generating to indicate to the web browser where to get the image from and where to display it in the html.

    jasonk,

    You are absolutely right, the code now runs without error but no graphics appear on the web page. Thank you for the education.

    Don't suppose you've seen any sample scripts that do what you describe?

    Thanks again.

      Your code has almost everything you need to accomplish it, you just need to save the image somewhere and include it in the page. You will need to setup a directory your script can write files to, which is also accessible from the web, but how to do that is dependent on your web server...

      my $img = join('.',time(),$$,'png');
open(OUT,">tmpimages/$img");
print OUT $gd->png;
close(OUT);
print "<IMG SRC=\"$img\">\n";

      Of course you will also have to change your script to emit text/html rather than text/plain for a content-type.
