Replace bitmap on multiple frames of an animation

I have a 12 frame animation made with Web Designer and was given all new graphics to put in. On each frame, I generally have a graphic that is shown and one at 99% transparency. I would like to simply replace the bitmaps, but the object on one page is shown and in the other it's not. Is there a way to replace the object just once and have it replace all the frames?

I am not sure if this will work, but you might drag and drop the new photo onto the existing photo. If the photos are duplicates then this should replace the others.

Hi this may be what you are looking for.
