Importing Photoshop Images

I'm making a simple animation, and the easiest way for me to draw things is to use layers in Photoshop -- copying over the previous "frame" (the previous layer) with slight changes.

What is the best and easiest way for me to import these into AE?

I know that I can put them into groups, but that's time consuming for some reason I end up with two copies of each image in AE.

Is there anyway for me to get AE to separate the layers into individual files? No layer has any styles, as of now.

Thanks,

Mike
