Help creating animated gif files!

[mattfraser]

Hi

i would like to be able to create animated wallpaper for my new mobile. I have found some on the net but having trouble creating my own.
Software i own are:

Paintshop Pro 8
Animation Shop 3
Photoshop 7

If i need any other software then preferably freeware.
I have attached a gif file of a animated wallpaper. It's this kinda thing i am looking to be able to design myself.

Can anyone help me?

Thank you

Matt
