use GD;
my $maxheight = 350;
my $maxwidth = 350;
my $srcimage = new GD::Image->newFromJpeg("Test2.jpg") || die;
my ($srcW,$srcH) = $srcimage->getBounds() ;
my $wdiff = $srcW - $maxwidth;
my $hdiff = $srcH - $maxheight;
my $newH; my $newW;

 if ($wdiff > $hdiff) {
     $newW = $maxwidth;
     $aspect = ($newW/$srcW);
     $newH = int($srcH * $aspect);
 } else {
     $newH = $maxheight;
     $aspect = ($newH/$srcH);
     $newW = int($srcW * $aspect);
 }

 $BigH = ($srcH * 2);
 $BigW = ($srcW * 2);
 my $newimage = new GD::Image($BigW,$BigH) || die;
$newimage->copy($srcimage,0,0,0,0,$srcW,$srcH);
$newimage->copy($srcimage,$srcW,$srcH,0,0,$srcW,$srcH);

# code for thumbnail $newimage->copyResized($srcimage,0,0,0,0,$newW,$newH,$srcW,$srcH) ;
 
 open(FILE, ">index1.jpg") || die "Cannot open index1.jpg: $!\n";
 print FILE $newimage->jpeg(80) ;
 close FILE;
 
print '<br><br><img src="http://www.thespenceroutfit.com/cgi-bin/Flyer/index1.jpg">';
exit;
