Bring clean transparent gif(s) into FlashMX

hi,
how is everybody doing? I am using PNG 24 as my primary image format for my flash animations but the image file sizes are pretty big. I wanna use Gif but whenever I import them into Flash they begin to have halos and unclean transparent background. How can I have a clean transparent background for gif’s if I am using PS’s Save for Web feature…thanks guys!
love,
omar

leave them as PNGs change the compression to JPG (in the properties in flash) and adjust the compression to fit your needs.

thanks
