Detecting animated GIF on the fly using PHP/CodeIgniter

animated-gif, codeigniter, gif, php, url

Solution

Check out this comment to the documentation for function imagecreatefromgif (on php.net). You still need to first download the image file even if you are just going to link to it later.

Problem

Is there any way to check if an image URL returns an animated or not GIF? I need to save image URLs and then show the images on my site, so I would like to allow GIF extension, but I need to avoid animated GIFs. Is it possible to detect that on the fly with out downloading the image?
