No matter what the Publish Settings (Flash CS3) on a simple Static or Animated GIF image -- I'm suffering a huge loss of color quality when published. I've even tried using a custom palette based on the original image (out of Fireworks). What's the deal? Thanks.
Gif is a max 8 bit format so colour will often be compromised on any image with gradients or complex colour.
Why7 would you want to publish gifs from within Flash? If Flash is worse in this respect than your other gif creation software, why not screen grab your Flash layout and take that into (e.g.) Fireworks?
Or are you placing a Fireworks gif on a Flash stage and not liking the result ..?
