<?php

$image = new Imagick("picture.jpg");
$width = $image->getImageWidth();
print "the image width is " . $width . " pixels";

?>

Will print:
the image width is 200 pixels

I am noticing that this is returning the original size of the image when it was opened, and not the size it may have been resized to with scaleImage or resizeImage.

"bob at majdak dot net" mentioned that this function does not return the resized image size.

I use this function in production code, and it correctly returns the width for an image resized with `resizeImage()`. 
I have not tested it with `scaleImage()`.
