Possible to work on all frames at once? (Image ready)

Hello all,

I have a graphic that has 57 frames in it. The only animation is a small figure in the center; the rest of the background is the same in each frame.
I would like to edit out most of that background, leaving just the center animation. I did this once before (on the same graphic, but I later deleted the result) and the only way I found to do it was to edit the back (after cropping) out of each individual frame, one at a time. UGH! Seems there's got to be a way to edit/erase the background from all frames at once. Is there an option/setting I am missing that will allow me to do that?
I don't use IR very often, so I apologize if this is a stupid question.

Thanks,

Ez

Hey, you can't post Image Ready questions here!

LOL! J/K. Sorry, I just couldn't pass up the opportunity.

... and I am even more sorry that I don't have an answer for your question... Just feeling funny today is all.

A good laugh is just as good as a a good answer if no good answer is to be found.
