How can i?

[color=black][font=Arial]How do I use a certain animation with a picture and then I reuse it in another part of the website changing the old pic to a new one without affecting that first animation with pic, for example I use a pic with a movie clip on the index page and on the portfolio page I use a new pic with the same movie clip, by just grabbing it from the library and flash wont recognize it as same, so I can use it as many times I want without flash thinking that is the same and give me problems.[/font][/color]
