This is the true story of what really happened to Carl Fredricksen and his dog, Dug. You didn't actually believe that balloon cover story did you? Carl did go Up, but it was evil aliens with a devious plot.
I've used Carl's house in this photo edit, but you can insert your own home or anything else that you prize. I'm using Photofiltre, a free image editing tool available at http://photofiltre.free.fr/. To see the finished, full size "Up-duction" please click here.
Step 1: Enter Evil Aliens
Next, right click on your house, select Copy. Right click on your UFO image and select Paste. Right click on the pasted image and select Paste Options. Check the Transparency box and set the Tolerance to 20. Right click on the image again, and select Transform, Free. Using the available options, adjust the image size, position, and angle. You can see the settings I chose in the included screenshot. Once yours is sized and positioned properly, click Ok.
