You can see that this instruction would save a lot of space; it would allow for a very small file to hold all the needed information to re-create the full-size image. (This is an oversimplification of the compression algorithms in image-editing software, but hopefully you'll get the idea.)

If you were to take the "compressed" file and open it up in your image editor, the software will look at the instruction "repeat for 1 million pixels" and do what it says. In other words, it reconstitutes the image back to its original size. That's what's going on with your files.
