I'm not sure exactly what you're trying to do, but if I'm going to combine two images I first create a new blank template (File>New) bigger than both images, then open each of the images as layers. Then use Layer>Scale Layer to change the size of each as necessary. Use the move tool to move each layer where you want it and you can choose which layer you want to be on top or bottom of the combined image by changing their order in the Layers Menu. When you're finished,crop the combined image from the white background template and export.
