Load pics in sequential order

I dont really ask alot of questions on here, i mostly answer others with half-educated guesses. So heres one of my rare questions for you:

ok… i have a vertical mc scroller that has a bunch of mcs in it. Works great and everything. Problem is, it takes forever to load the images at it tries to load them all at once(obviously). Is there an easy was yo preload them before they are displayed in order from top to bottom? I dont need a loading bar or anything, i just figured if they load sequentially, the top ones will be immediately visible and the bottom ones will be loaded by the time the user gets there.

Currently i am playing with the idea of putting something like this in mc:


if (pic1._framesloaded = _totalframes){
etc...

Is there an easier way to make this happen? I just want to load the next image after the previous one is displayed.
