Save these: here and here.

Step 1
Now open up the images in PSP and open up a new image whatever size you want. Mine is 500×300.

Step 2
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.

Step 3
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.

Step 4
Now choose the eraser tool and start erasing away some of the overlapping part.
