Transparent Animated GIF Showing Previous Frames...

[Chris Ward]

Hi and thanks in advance for any help. This problem is making me tear out what's left of my hair...

I've created an animated gif which I need to have a transparent background. It displays fine within Photoshop (CS4 on Vista), but when I save it for the web and set the background to transparent, the final animation displays all (three) of the frames, creating an unwanted "ghosting" effect. When I save the animated gif without a transparent background, there is no problem and each frame overwrites the last, as required. But it must be transparent. I have looked high and low online for a solution to this problem but can find nothing. I can't even understand why this behaviour would ever be wanted.

Any help would be greatly appreciated.

Thank You.

Chris.

Solved! I idiotically had the frames set to "do not dispose".

'ghosting' can be useful for certain effects
