Looping a dynamic slideshow

I’m working on a flash slideshow with transitions that I need to loop smoothly. I have four movie clips, one on each layer and each one loads and fades on top of the previous one. When it loops back around to the beginning, I don’t get a a smooth transition. I get white space for a few seconds. On the last frame I have gotoAndPlay(1); and on frame 1 I have my loadVariablesNum statement.

Any tips on how to loop this seamlessly?
