Gif Animator Program?

Hello,

I have Parallels desktop on my Mac and run a Windows virtual machine. The only reason to have it is that I get used to use uLead gif animator. However I want to get rid of the Windows virtual machine. So please "save me" by recommending a easy to use gif/png/jpg animation program which will allow me to create banners.

Thanks

GiftedMotion works, if you can put up with it being a java app.
