The Lightbox scripts have been created to make animating 'Frame by frame' easier and more intuitive in Gimp.
It does this by trying to emulate animating traditionally.
The scripts helps organise layers into separate sections allowing Frames, Colour and Backgrounds.
These can all be added and organised from the Animate menu which the script adds.
These layers can then be viewed, composited and exported as an moving animation, .gifs or .tif image sequences for editing.
