Animated GIF not working in browser Options

[klarko4444]

Hello,

It's me again I am a full time athlete and part time designer so I am still learning some basic things here, thanks for your patience and thank you in advance for your help

I have created a simple animated GIF using Fireworks CS3 for a website I am updating. It is a bunch of images, chosen by my client, that loop around and around. I have added a bit of a fade between them by using varying opacity degrees of duplicate frames. It plays perfectly in Fireworks but when I preview in browser, the fade does not show up. I have tried reseting safari and emptying the cache...any suggestions as to what is going wrong?

Thanks again.

Claire.
