Re: gif image

Hello Valeri and Rene,

gifsicle has '-O' option for optimization. But 'convert' cannot create optimized animations.

I checked hsumanim.C, but '-O' option is not used. I think 'convert' is good enough for this tutorial if you do not need to optimize the animation.

Please try '-O' or '-O2'.
w/o optimization => 180KB
-O => 150KB
-O2 => 93KB

Sincerely,
