Ugly white outline

I know this has been covered somewhere but I can’t seem to find it again.
I’ve been hand drawing frames and importing them into TBS from photoshop in PNG format. The problem is every frame I import has a nasty white or yellow glow around the image that sticks out like crazy once I’ve exported to QT.
Just wondering if someone could help or possibly redirect me to the previous post that covered this problem.

nevermind, i found it
