Find image dimensions (width x height) for list of image URLs

Is there any known way to extract the width and height of a list of image URLs?

I found a solution, though not ideal....

I created a short PHP script:

echo $_GET['imageurl']. "<br />";

list($width, $height, $type, $attr) = getimagesize($_GET['imageurl']);

echo "Image-width: " . $width;
echo "

";
echo "Image-height: " . $height;

Have this hosted on a server I control. Then using RegexpFindOnURL in SEOTools For Excel I'm able to extract the data.

Nice solution. I have plans for future versions to build a solutions for this.
