Ok, things have been going well with learning about how to use the nice GD module to create random images, etc. However, I have stumbled accross a problem I was having earlier, but didn't say anything much about until now. I have the following 2 files, and here they are in their basic code form:

File: gd1.pl
#!/usr/bin/perl -w
use strict;
use GD;
my $im = new GD::Image(100,100);
my @colors; # Preallocate colors, since PNG has a limited number of co
+lors
for (0..255) {
$colors[$_] = $im->colorAllocate(int(rand(256)),int(rand(256)),int(ran
+d(256)));
}
for my $x (0..99) {
for my $y (0..99) {
$im->setPixel($x,$y,$colors[int(rand(255))]);
}
}
print "Content-Type: image/png\n\n";
print $im->png;

File: gd2.pl
#!/usr/bin/perl -w
 
print "Content-type: text/html\n\n";
print<<HTML;
<html><head><title>testing more</title></head>
<body bgcolor=#ffffff>
<center>
HTML
print "Content-type: image/png\n\n";
print "<img src='gd1.pl' height=100 width=100>\n";
print<<HTML;
</center>
</body>
</html>

And I was trying to figure out how I can use regular HTML code to run this random png image creator program over the internet, so it would look like it was a regular png already on the server.

My guess is there is something really wrong with the gd2.pl file since I haven't tweaked the original gd1.pl actual program file all that much.

Thanks for any help or input I could get!
