Still working on that CD?

A few ways for that image, only two edges needed.

Give the image transparency, Layer -> Transparency -> Add alpha channel.

Resize the canvas, quarter inch needed? (I added an 1/8" but should be 1/4") and
drag the image to the top - right corner, gives a transparent edge left and
bottom.

Then you could get away with just filling the transparency with a dark colour,
ie. lock the pixels and then fill.

A better way might be with the resynthesizer + heal transparency plugin. You
have that plugin ?

And with the original over the top the new edge looks like this:
