For panaromic type situations you might want to look at hugin, which is designed for exactly that
Brett++, I've just been trying out hugin and it's fantastic and does just what I expected. I had a load of holiday photos lying around that I'd planned to sew into various "epic" panoramic shots.
Having done a few now, they're not quite as epic as I'd hoped but pretty good :)

My thanks too, Brett, for the hugin suggestion. It looks very interesting, and clever. However (see below) it didn't cooperate with me on this occasion!
Meanwhile, I finally managed to suss out the basics of doing it with the GIMP. It's basically a matter of playing with layers, and using the "move layer" button in the main menu (like a cross with arrow-tipped arms) to move the layers around. However, I would also need to play with the rotation and re-scaling options to get things really right.
One thing I found difficult (but I'm probably missing a GIMP trick here) was getting the horizontal positioning right. I had taken a series of 5 photos, with considerable horizontal overlap, to give myself a pool of keypoints to work with. But when one layer was being slid over an adjacent one, it hid the one it was being slid over, so positioning was a bit hit and miss.
If anyone would like to try to do better, my material is at:

The 5 photos (in the original large format -- again see below) are (in order from Left to Right):
glfarm01.jpg glfarm02.jpg glfarm03.jpg glfarm04.jpg glfarm05.jpg
and my (somewhat cack-handed) attempt at a panorama using the GIMP is:

And, while you're at it, you can enjoy our local wild peacock strutting his stuff in:

I woudl be interested to see what other can achieve, either using the GIMP in a more sophisticated way than I did, or by using hugin.
When I tried hugin, it didn't like the raw material! I could get as far as "Align" in the "Assistant" menu, with 2 or 3 of the primary images (e.g. 01 & 02, or 01 & 03, or 01 & 02 & 03), but id didn't like the full set of 5:
Warning 10 unconnected image groups found:[0], [1], [2], [3], [4], [5], [6], [7], [8], [9] Please create control points between unconnected images using the Control Points tab.
After adding the points, press the "Align" button again
And even, using only 01 & 02, when the result of "Align" came up OK, when I clicked on "Create panorama" it failed, simply producing a blank result. I would be interested to see how other people manage!
Incidentally, I had used ImageMagick's "display" to create reduced-size versions of those 5, to make it easier to play with lining them up on screen. Each was 576x432 in size. Using these, hugin simply didn't want to know: no result whatever from "Align".
By the way -- since we're on that particular web-page of mine, Brett: You wrote that "montage actually creates a montage of thumbnails, so isn't quite right." I don't think that's true!
Have a look at the photo: reflections.jpg on that same web-page: http://www.zen89632.zen.co.uk/LtOuse
This was taken one very very calm February afternoon.
Later, I played with this. First I reflected it upside down. Then I reflected each of these left-right. I then used montage to combine them, so as to produce the image: symmetries.jpg on that web-page.
Best wishes to all, Ted.
