Hi guys, I am still having problems with parsing an image's size from a URL (not local path).

Sometimes it determines the size, sometimes it doesn't and I can't quite figure out what the problem might be.

Also, the sizer at the bottom adds only images that are TOO BIG or HAVE NO SIZE and I need the opposite, that's sort of a bug, too, that I can't fix.

Can someone help with one or both of these issues? 

   if ($limit_img_size)
   {
      @image_urls = grep {
         my $this_url = $_;
         my $image = get($this_url);

         print "Getting size of image $this_url<br>";

         my ($height, $width) = imgsize(\$image) or die "Error $!";

         print "IMG $this_url is $height and $width<br>";
         $height <= $max_height && $width <= $max_width  && $height ne
+ "" && $width ne ""
      } @image_urls;
   }

   push @found_images, @image_urls;
}

Here is some output of my last run. All image URLs do work but I wouldn't suggest users go to them as who knows what they might be.
