If you are already creating them dynamically, you can turn that portion into a separate CGI script. Use that CGI script as the SRC value in the IMG tag.

<img src="http://www.example.com/cgi-bin/make_graph.cgi?values" />

Your CGI script has to return the right MIME type, such as "image/png" or something else.

Once you put those things in IMG tags, you just use the tags in the HTML like any other IMG tag.

Thanks, this worked. As you suggested, I used the CGI script itself as the image. Passing an argument of 1..4 in order to tell the script what image I wanted.

<img src="/cgi-bin/trend.cgi?image=1">
<img src="/cgi-bin/trend.cgi?image=2">
<img src="/cgi-bin/trend.cgi?image=3">
<img src="/cgi-bin/trend.cgi?image=4">

The CGI script, or course, accepted the param and returned the corresponding image.

For a recent customer service data project, I needed several GD::Graphs and simply duplicated my call to individual code for each graph:

print "<img src=http://www.url.com/cgi/custsvcgr.pl>";

#!/usr/bin/perl -w


use GD::Graph::bars;
...get data here...

my $mygraph = GD::Graph::bars->new( 600, 350 );

$mygraph->set( dclrs => [qw(green pink blue cyan)] );
$mygraph->set(
    x_label => 'Section',
    y_label => 'Satisfaction',
    title   => 'Customer Service By Question',
    bar_spacing => '5',
  )
  or warn $mygraph->error;

my $myimage = $mygraph->plot( \@graph )->png;
print "Content-type: image/png\n\n";
print $myimage;

I think you will find other examples similiar to this one with a super search.
