This is the function I use to return the filesize of a remote image.

function ffilesize($file){
    $ch = curl_init($file);
    curl_setopt($ch, CURLOPT_NOBODY, true);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HEADER, true);
    $data = curl_exec($ch);
    curl_close($ch);
    if ($data === false) 
      return false;
    if (preg_match('/Content-Length: (\d+)/', $data, $matches)) {
      return (float)$matches[1];
      }
    elseif (preg_match('/content-length: (\d+)/', $data, $matches)) {
      return (float)$matches[1];
      }
} 

I use it on lulzimg.com which is a very heavy traffic site with thousands of images uploaded everyday. And it IS very fast. If it's slow for you, maybe your server's on a congested network or the target urls are responding slow.

Still slow

I have another question.
What will be the fastest way to check if remote image exist ?
Maybe i can use again the filesize ? 404 and the other errors have no filesize or it is in bytes?

Its tour server dude, maybe CPU?

i don't think that there is any faster.

but why don't you just store the images on your own server (resized) ?

What exactly are you trying to do. Where are the images and what are you trying to do to them. We may then be able to offer a better way of doing it.
