A friend and I are struggling to get this little segment of code to work. Basically all we are doing is generating some graphics on the fly from a MySQL database and displaying them on a webpage.

The problem is that this section of code does NOT display the generated image - but if we set the img src to a previously generated image it will happily display that.

The image itself is generated fine - but why can't we get the new one to display?

if(param("submit"))
{
        $start=param("start");
        $finish=param("finish");
        

        if(!defined($child_pid=fork()))
        {
                die "cannot fork $!";
        }
        elsif($child_pid==0)
        {
                
                my $query= "/usr/apache/cgi-bin/order/ldasdump.pl -png
+ -d dicty chr5.1:$s
tart,$finish --user xxxx --pass xxxxxxxxx > /usr/apache/htdocs/nob24.p
+ng";
                exec($query);
                
        }
        else
        {
                
                waitpid($child_pid,0);
                print img({src=>"../../nob24.png",align=>'LEFT'});
