Animation Question

Alright, I've checked the memories, but nothing I am reading is making sense.

I am using Image Ready 7.0.

I want to make a graphic in which the picture stays the same throughout, but the text changes(And there are several frames of text). I want to picture to stay stationary though.

The solution is probably something simple, but I am so clueless. I am thinking it has something to do with tweening, but I dunno!

Can anyone help?
