amazon s3 - AWS SDK PHP version 2 - retrieving image dimensions?

Question

Is it possible to retrieve the dimensions of an image stored on Amazon S3?

If the answer is no, are there any other ways around it other than downloading the image to my server to which sounds inefficient?

I'm using version 2 of the AWS SDK for PHP.

I've been looking through what is returned from the following code but doesn't seem to give dimensions.

$result = $s3->getObject(array(
    'Bucket' => 'BUCKET_NAME',
    'Key'    => 'KEY_NAME'
));

var_dump($result);

Answer 1

I'm not 100% familiar with SDK2. With 1.5 you could do this

getimagesize($s3->get_object_url($bucket,$filename)); 

I think this is still possible as long as you can access publicly the image (or you have to find your way around authorized urls)

Obviously, your php must be enabled to open remote files.
