MovieClipLoader Class - Help Please :D?

Using the ‘MovieClipLoader’ class I would like to be able to preload several .jpg images (with a progress) bar, one after the other, after the other etc… Going in order… Before the rest of the movie continues to play. Maybe using a for loop or something.

How can I do this?

Only reason for the loop is so that the amount of .jpg images that are loaded can be dynamic.
