It is a older freeware version but you can get Ulead Gif Animator 2.0 here.
www.pricelesswarehome.org/2006/PL2006GRAPHICS.php#Editor:GifAnimations
or download it from here.

It is not as easy to use as version 5 is and if you get PhotoImpact from Ulead then Gif Animator comes with it so it makes it even more easy to use because you can edit things better. But they are not free.
