Making an Image Transparent.

Making an Image Transparent.
Not the background! The actual image. I don't understand how to use 'opacity'. I move the slider and nothing happens!

Can someone give step-by-step instruction on how to make an entire image appear faint?

Add an alpha channel to the layer (without one it cannot be transparent): "Layers/Transparency/Add alpha channel". Then the opacity slider will be operative. Save in a format that support partial transparency: PNG

I've added the alpha channel but the slider just converts the image into a chequerboard.

The checkerboard is the "canvas" (the "drawing board"). If you see it, it means your image is (partially) transparent. If you display your image over something else (in a web page) then you'll see whatever the image is displayed over.
