RemoteImageInfo

FastImage finds the dimensions or filetype of a remote image file given its uri by fetching as little as needed, based on the excellent Ruby implementation by Stephen Sykes., _(*1)

Usage

<?php 

require 'RemoteImageInfo.php';

$uri = "http://farm9.staticflickr.com/8151/7357346052_54b8944f23_b.jpg";

// loading image into constructor
$image = new RemoteImageInfo($uri);
if($image->checkLoad()) {
    list($width, $height) = $image->getSize();
    echo "dimensions: " . $width . "x" . $height;
}


// or, create an instance and use the 'load' method
$image = new RemoteImageInfo();
$image->load($uri);
if($image->checkLoad()) {
    $type = $image->getType();
    echo "filetype: " . $type;
}
