Go to this web page http://fence-post.deviantart.com/art/Col...-153804862 Top of the page is a download button to download a zipped file color_to_alpha_all_layers_by_fence_post-d2jkkla.zip
Unzip that and put the script fp-script-fu-color-alpha-all-layers.scm in your Gimp profile scripts folder C:\Users\your-name\.gimp-2.8\scripts.
Start up Gimp, open the gif file, change the color mode from indexed to RGB Image -> Mode -> RGB Some color operations do not work with color indexed files.
Start the script from Colors -> Color to Alpha All Layers. In the dialogue click in the Color to make transparent and choose black (white is default colour) Ok everything to apply
looks like this: http://i.imgur.com/15xSv6Q.jpg
Gives this: http://i.imgur.com/ePvqK8A.jpg just one layer showing, the swirly nature covers a lot when all layers are showing.
If you are going to do more editing, save your work as a Gimp .xcf file.
When completely finished, export as an animated gif and it will be converted back to color indexed mode.
