Thanks for the suggestions. I tried using undef $im but I still seem to have the problem. The following code builds 10 images. The first one has a white background and the rest all have black backgrounds. I am not sure why. I would expect them to all be the same. Any suggestions? Thanks again.

Here is the code 

#!/usr/bin/perl
use GD;
$maxx = 600;
$maxy = 500;
for ($x = 0; $x < 10; $x++)
{
        # create a new image
        undef $im;
        $im = new GD::Image($maxx+50,$maxy); 
        $im->trueColor(1);
        # allocate some colors
        $white = $im->colorAllocate(255,255,255);
        $black = $im->colorAllocate(0,0,0);
        # make the background transparent and interlaced
        $im->transparent($white);
        $im->interlaced('true');
        # Put a black frame around the picture
        $im->rectangle(0,0,$maxx-1,$maxy-1,$black);
        $im->line(0, $maxy/2, $maxx, $maxy/2, $black);
        $png_data = $im->png;
        my $file = "TestImage". $x.".png";
        open(DISPLAY,">$file") || die "open failed";
        binmode DISPLAY;
        print DISPLAY $png_data;
        close DISPLAY;
        print "Output file = ".$file."\n";
        undef $png_data;
        undef $im;
}
