If you use a high pass filter on the image before doing this, the tiled
image won't have bright and dark diagonal lines. The Gimp doesn't have a
built in high pass filter, but you can get the same effect like this:
1. Flatten the image if it is not already a single layer.
2. Duplicate the layer.
3. Gaussian blur the top layer with a large radius.
4. Set the top layer's blending mode to grain extract.
5. Flatten the image again.
Since this will remove the overriding colour of the texture, add it back
in using colour balance, levels, or colour curves.
Thanks for the tip.
P.S. I just tried it on a more difficult pattern (irregular stone bricks
in a wall), and it doesn't work nearly so well.

You can make tiles with Enblend for some strong patterns by
straightening the image with Hugin and cropping the image at measured
points. This is easy for regular bricks, but I don't think it will work
with irregular stone bricks. The Texturize plugin for the Gimp might be
worth a try:
http://gimp-texturize.sourceforge.net
I just tried texturize on the stone image and it looks better than
anything I've tried so far, so I'll probably be using this from now on.
Thanks :)
