You don't really need to check whether the image is 800x600 or 600x800, actually.
Image::Magick will do that on its own if you convert to '108x108', converting the longest side to 108 px, and the shortest to whatever it would proportionally amount to.
Here is some code I've been using to generate an HTML index for images files, with thumbnails :
#!/usr/bin/perl
use strict;
use warnings;
use utf8;
use Image::Magick;
my $dir = $ENV{'PWD'};
chomp(my @files = `ls $dir`);
if (-e "$dir/thumbs") {
print STDERR "The directory $dir/thumbs already exists. Files inside
+ may be replaced.\n Do you want to continue ? (y/n)";
chomp(my $choice = <STDIN>);
if ($choice =~ /^n/) {
print STDERR "Aborted by user.\n";
exit(1);
}
else {
if (!($choice =~ /^y/)) {
print "Please enter 'y' or 'n' :";
}
}
}
mkdir "$dir/thumbs" || die "Unable to create directory $dir/thumbs :$!
+";
if (!(-e "$dir/index.html")) {
open (OUT, ">:utf8", "index.html") || die "Unable to open file $dir/
+index.html : $!"
}
print OUT <<HERE;
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w

foreach my $file (@files) {
if ($file =~ /\.(jpg|jpeg|bmp|gif|png)/) {
my $image = Image::Magick->new();
$image->Read($file);
$image->Resize('150x150');
$image->Write("thumbs/t_$file");
print OUT "<a href=\"$file\"><img src=\"thumbs/t_$file\"></a>\n";
}
}
print OUT "\n</body>\n</html>\n";
close OUT;
