I am using Gimp, I have an RGB image on one layer (alpha unused), I then created another layer it now has the alpha I want (RGB) unused.
I can not work out how to get the alpha to the other layer. How can I get the alpha from one layer into another layer?

For each layer...
Now you should see that both layers have two "preview" boxes in the Layers panel.
Now...
This should provide you with the results you want. I would also delete the layer (or at least make it invisible) that doesn't use RGB at all after this, but I suppose it's not necessary since it's transparent.
