I have an animated GIF of the planet Earth spinning on its axis. Whoever created the GIF has the planet spinning in the wrong direction.

I am trying to use ImageJ to deconstruct the GIF file and reassemble it in reverse sequence.

I have installed the plugin for importing an animated GIF file, and I've used the Stack -> Image feature to deconstruct the animation into its individual images.

But, I can't seem to figure out how to recombine the images in a different sequence.

Can someone please help?

Thank you.
