Whys flash converting my .gifs?

im currently making a tile game based off of TonyPa’s tutorials. but…im having a zelda animation for walking, and im importing .gifs for the different frames of the walking animation, but its converting it into .bmp’s! not letting me do the transparent-ness that .gifs can do. why is flash converting the imported .gifs into .bmp and how can i change it? :puzzled:

and btw: its doing this fuzzy effect on the picture also, i just want plain pixel style lookin pictures, not blurred ones :\
