The greyscale image is an alpha mask for the other image, hence the "_a" at the end. This means that it basically has the transparency information for the other image; black is transparent, white is opaque, and everything in-between is... in-between.
To apply this in GIMP, you can use either of the methods explained in the first answer to this question. I used method 1 and it worked pretty well with these, if you do it with the original high quality images it should come out perfect.
If you're using Photoshop instead then you'll have to find another tutorial but I assume it would be a similar process.
