Merge down/add a layer on all layers bellow it with GIMP

Question

I wanted to add some text on an GIF animation. After downloading few GIF editors and finding them all complete crap, I opened GIF in GIMP.

GIMP displays every step of the animation as a layer:

I expanded the whole image to contain my text:

And I created a layer containing some text, which I carefully positioned exactly above the image:

But the problem is, how can I add that layer easily on all 30 (or even more) steps of the animation?

Answer 1

You need a script, for instance interleave-layers in "title" mode.

Answer 2

Well, other way its in the layer dialog, You can do this toggling between the duplicate layer button on the right and the raise up layer arrow button on the left. But indeed, when its too much its better to do the script.

Good luck!
