Now open up the images in PSP and open up a new image whatever size you want. Mine is 500×300.
Take the fist image here and press CTRL-C and paste it into the transparent image by pressing CTRL-L and move the picture around with the Move Tool until it gets to where you want it.
Now take the other picture and copy it and this time press CTRL-L onto the transparent image. Now click the Move Tool (or M) and move the picture you just pasted around until it’s somewhat like this.
Now choose the eraser tool and start erasing away some of the overlapping part.
