Using GIMP, what is the easiest way to repeat an image in a tiled fashion?

I have an image that is 100×125 pixels in size.

I'd like to create a new image by repeating the source image, five times, horizontally (so the new image is 500×125px).

The repetitions must be pixel perfect, in exactly the right place (so I'm less likely to accept an answer that requires placement by eye-balling).

What's the easiest way to do this using GIMP?

Solution 1:

1. In the menu, navigate: Filters → Map → Tile....
2. Disconnect vertical and horizontal scales (break the "chain" between them).
3. Switch the units to percentage (%).
4. Enter 500% for the width, 100% for the height.

Solution 2:

Don't have GIMP at hand right now but have you tried: Filters > Map > Tile?
