How do I combine images with gimp (Linux) ?

With Linux, I use the program Gimp to edit my photos. I was able to post one image on top of another, but how would I make these two images into one?

soln:-

Open picture one, and click "Image->Duplicate" to get a third Image. Now open picture two, and copy & paste it into the new picture, picture tree. Activate the move tool (the button with the crossing arrows). You can move the pasted next to the duplicate of picture one, but it gets invisible. Now choose "Image->Fit canvas to layers", to make the canvas big enough for both images. To make the pasted image visible, click "Layer->New Layer". Now click "Image->Flatten image", and they are combined
