Transparent image with GIF? (white spots)

[itsuniquexp]

Hii. I've been having a problem. I was trying to make a signature earlier with gif on photoshop cs5. I tried making it with a transparent background and when I put it up on the forum, it gave me white spots. It's not noticeable with a white background as the spots are white, but with another color background, it would show. Can someone tell me why?

-- this is the image i made with a transparent background. and because it didn't work out, I decided to not use a transparent background and used a color of the background of the forum which was off gray.


I know i have erased all of the white spots in the transparent file because when i didnt make it gif, and saved it as a jpeg without the animation, it was perfectly fine..



Can someone fill me in on as to what i am doing wrong?
