Glowing Animations help

[zayber]

I'm making an animated banner for my RPG's new event. Anyway, its rather long, and the last time I tried, I saved it as a gif. and it uploaded all pixally, especially on the glows. So is there anything I can do to prevent this from happening?

Was it all pixelly after you saved it but before you uploaded it? Or did it get that way after you uploaded it.
