I was wondering if you can load an external jpg into a movie clip which is in the library?

The reason I am asking is because I have a transition between loading images and the transition has several instances of one movie clip being used for different tweens.

The problem is that when the image loads, all instances have to be in frame 1 otherwise the jpg won't load into them and because I am using tweens the instances are on all different frame numbers.

I want to be able to load the jpg into this movie clip but in the library so it updates all of the instances of this movie clip on the stage and further down the timeline.

Is there a way of doing this or an alternative method I can use?
