- If your base layer name is printed in BOLD in the layer dialogue, right click on it and "add an alpha channel". - again right click on the layer and add an layer mask, filled with white. - take the gradient tool with a gradient from black to white. - apply the gradient to the layer mask (just paint into the image if the frame around the layer mask is white) Start where you want to have 100% opacity and end where you want 0%.
