Great let's get started:-
1. First thing to do is take two pictures of yours. While taking your pictures utmost care must be taken that the camera (and other objects in the scene) are not moved. Try to make sure that everything else except you in the pictures should remain still for the example following are the two pictures i saw in the tutorial (i do NOT rip)

2. Next thing you need to do is open your two images in GIMP. You can do these by clicking "File>>Open as Layers" to open the two images as two layers. You now should have something like this:

3. Next hide the first Layer (click on the eye against the first layer in the layers dialouge)
4. Take the "Scissors select tool" and use it to select the person in the second layer. Try to keep the selection close to the person.
5. Grow the selection by clicking Select>>Grow so that some more area around the person is selected. I grew the selection by 20px. You should have something as below:

6. Make the first layer visible (make sure the selection is not lost). Right click on the layer and select "Add layer mask". Select "White (full opacity)" in the dialog and click "Add". You should see that there is another white layer added to the right of the first layer.
7. Click on the layer mask added, select the "Bucket Fill Tool", make sure that foreground color is set to black and the selection is still there. Click inside the selection. This should fill the selected area on the layer mask with black colour. Also, the person in the second layer should become visible. You can lose the selection now.

8. It's almost done, but there might be some sharp color changes around the second person because of the change in the lighting. To Fix this we will blur the layer mask a bit so that the colours of the two layers are blended. Select the layer mask and select gaussian blur from "Filter>>Blur>>Gaussian Blur". Select radius something less than how much we grew the selection, I used 17px.
9. DONE!!!
