Need help with fading images, source posted!

hi everyone, i have put up my fla file because i am at a loss for how to solve this issue. ive been trying to figure it out for a couple weeks and i would really appreciate any advice or suggestions. basically what i want to happen is to have the images that are loaded “randomly” to fade out/in. How do I do that?
