PNG transparency not working when importing in AfterEffects

I have been saving the pictures for Web & Devices -- PNG-8, transparency is checked, as far as Matte goes, I've selected "none" .... however, when I upload the images into After Effects, they all have white backgrounds instead of being transparent! I have combed the archives and can't seem to figure out what my problem is. If I ticked transparency, shouldn't it be transparent??

Even with transparency selected, if I do click Matte, it will use that color as the background in AfterEffects. But especially if I have "none" selected for matte, why is there a background showing up? I realize that I could try PNG-24, but file size is absolutely essential, down to the kilobyte, so I need to keep it at PNG-8.

No. AE doesn't do palette based transparency. The image is not really transparent, it's just one color being tagged as such that a rendering device (browsers for instance) will blend in teh background pixels in place of the color. It just doesn't go together with how AE works. As Rick said, you will have to use 24bit PNGs.

when you say "You'll have to use PNG 24" do you mean i have to use PNG24 only or a PNG type that's 24+ like PNG24, PNG32, PNG48 and PNG64?
