linux console get image size

On linux console, if you need to get an image size, and imagemagick is not installed, you can use the following script (save it as "getimgsize.php", chmod +x, then run it with your image file":


#!/usr/bin/php -f
<?php
if ($argc<2){
        die("Usage: getimagesize IMAGEFILE\n");
}
list($width, $height, $type, $attr) = getimagesize($argv[1]);
echo "Size is $width x $height\n";
