Determine Image Size from URL

Need to get the size of an image on the web without storing it.  Done by pulling the image with LWP::Simple and giving the content buffer to Image::Size.

#!/usr/bin/perl
# Get dimensions of web image

use strict;
use warnings;
use LWP::Simple;
use Image::Size;

my @urls = (
	"http://www.google.com/intl/en_ALL/images/logo.gif",
	"http://l.yimg.com/a/i/ww/beta/y3.gif",
	"http://www.example.com/nothing.gif",
	"http://graphics8.nytimes.com/images/misc/nytlogo379x64.gif",
);

URL:
for my $url (@urls) {
	my $image = get $url;
	unless (defined $image) {
		warn "Couldn't get $url!\n";
		next URL;
	}
	my ($width, $height) = imgsize(\$image);
	printf "%4d %4d   %s\n", $width, $height, $url;
}

exit 1;
