I have been tweaking more of the tiny code snippet that I have been working on (thanks again to myocom for the original snippet.

Currently, it works fine, but I would like to know if there is a way I can make the pixel size a lot bigger or smaller. Can GD do this? I have read through the documentation at Lincoln Stein's site where the module comes from, but it doesn't seem to have any additional commands for the "setpixel" command.

Here is the current code snippet:
#!/usr/bin/perl -w
use strict;
use GD;

my ($width, $height) = (300,50);
my ($rvalue, $gvalue, $bvalue, $total) = (255,255,255,256);
my $im = new GD::Image($width,$height);

#Allocate the colors that are going to be used
my @colors;
for (0..255) {
  $colors[$_] = $im->colorAllocate(int(rand($rvalue)),int(rand($gvalue
+)),int(rand($bvalue)));
}

# Create image according to height/width proportions and given amount 
+of colors
for my $width_length (0..$width-1) {
    for my $height_length (0..$height-1) {
        $im->setPixel($width_length,$height_length,$colors[int(rand($t
+otal))]);
    }
}

# Set binmode to STDOUT
binmode STDOUT;

# Set output to be an image for CGI
print "Content-Type: image/png\n\n";

# Standard output of created image
print $im->png;
