how do i make gif pic's invisible

i mean when i make a monkey how can i make the Bg invisible??

u get this?

Get IrFanView.
When u save the gif select "Save transparant color" then chose the color

thx : )

u know a good program to make gifs in without losing to mutsh details

EDIT: oh u can use the program for that too

Nice ava.

Maybe a PNG woulda been better, but you lost almost no detail of colour...
Still nice.

Interesting proggy

It also has alot of plugins, which make it play almost every multimedia format. With it's fast starting up, I have it as standard program for running most of my files :)
