At the high level, this looked trivial. That's why I was surprised that I couldn't get gimp to do it. All I wanted it for was to have a picture I could use as a background across my dual monitors!
These instructions were exactly the level I needed for my first go, thanks Stephen. (Even then it took three goes to get right!) It has been an excellent learning exercise as well. Just the differences between canvas size, layer size, layer postion, copying all of a layer, ... I'm glad I did it in gimp, now I might stand a chance doing the next thing! Kerry.

Step by step instructions: 1. Open the image in gimp 2. Make the canvas twice as wide: menu Image > Canvas Size 2.1. Unlock the aspect ratio: click on the chain icon between the width and height checkboxes 2.2. Set the width: double the number in the Width field; in my case, I changed 500 to 1000. 2.3. Apply the changes 3. Make the layer the same size as the image: menu Layer > Layer to Image Size. Otherwise your new copy will not be visible... 4. Select, copy and paste a copy: ctrl-A, ctrl-C, ctrl-V, or menu Select > All, menu Edit > Copy, menu Edit > Paste. This makes a 'floating' layer. 6. Move the copied 'layer' to where you want it 6.1. Use the mouse 6.1.1. Select the Move tool in the main gimp window 6.1.2. Drag the image to the right and tweak it exactly into position 6.2. Alternatively, offset the layer 6.2.1. menu Layer > Transform > Offset 6.2.2. Set the X offset to the original width (in my case, 500) 6.2.3. Set the edge behaviour to Transparent (rather than Wrap, otherwise you will only be able to see the offset copy) 6.2.4. OK. 7. Anchor the floating layer: ctrl-H or menu Layer > Anchor Layer. This copies the floating layer onto the original image. 8. Save the whole thing. Stephen
