Load multiple external images dynamically?

I’m probably being an idiot here but is it possible to load a series of images into a dynamically created movieclip? I’m under the impression you can’t create an empty movieclip and add frames to it dynamically?
Basically I would like the equivilant of loading a series of images into flash and placing them on seperate frames in a movieclip so they animate when the movieclip is played?
