Sprites for RPG Maker XP

[Spawn of Sephiroth]

ok, i have downloaded some ff charactor sprites from the internet. but the problem is that when i get the charactors put in, they have a white square around the body while it moves. how can i get that off.

When importing the set, right and left click on the background. It will make that color transparent.
