The reason I asked you to upload them to imageshack is so we could see them. Do you have a link?
Anyway, do you want animated flames or just static flames? Animating flames will be alot harder but can be accomplished.
Anyway, to animate something simple, make the frames that you want to show in animation (ie in a banner, text that moves or changes) and make all the frames on differen layers. Then click the "edit in imageready" button. Make sure you have the animation and the layers box open (Window > Animation and Window > Layers ). Make the first frame layer visible and then click the new frame button in the animation box. (second from the right) Next make the second frame layer visible. Carry on until you have the whole image animated. To adjust the time for which you want the frame to be shown, click the little arrow in the bottom right of the frame in the frame box. Have a play around and you should get the hang of it in no time
