Handling animated images with PHP

Question

I already wrote a PHP script that allows users to upload images but I want to be able to allow my users to upload animated images. What do I need to add to my current code to allow animated images using PHP? A quick code example would help me out a lot.

Nothing. Animated images are images all the same.

EDIT: If you are resizing your images using GD, you'll lose the animation, since GD can't handle it correctly.
If you have the ImageMagick plugin installed, you should use it instead of GD:

$thumb = new Imagick('myimage.gif');

$thumb->resizeImage(320,240,Imagick::FILTER_LANCZOS,1);
$thumb->writeImage('mythumb.gif');

$thumb->destroy();

Answer 2

If your script accepts gifs and pngs you should be all set.
