Open RGB image. Add an alpha channel (Layers->Transparency->Add Alpha Channel) Add a layer mask (Layers->Mask->Add Layer Mask) Open grayscale image - copy into layer mask you just created (Edit->Copy in grayscale image, Edit Paste with Layer Mask active in the RGB image) Optionally, apply the layer mask (Layer->Mask->Apply Layer Mask). -- Michael J.
