This is a PNG image, not an animated GIF.
This is backward-compatible with old browsers like Internet Explorer 6.
It works with 24-bit true color PNG images and images with transparency.
Note that you can not right click and save these animated images.
If you do, you will get a still image.
This script is in the public domain, meaning that you can use
this script on your wesite without paying royalties and without
including a link back to

Note that this script was written years ago and is pretty much obsolete.
you should consider using HTML5 video instead. Download
