You have to download Gimp to use it. And it is not cutting, you have to basically put layers on top of each other.
Let's say you have the BackGround Layer and you open it with Gimp. Then you have the girls picture and you open it. Let's call it Charmed Layer.
You have to go on the Charmed Layer, copy it by pressing Ctrl+C [tell me if it is wrong >.<], then you go on the Background Layer and press Ctrl+V. You press on the Move Tool and move the girls where you want them to be, and then...
You go to the Layers Window, and press Create a New Layer, Right-Click on the Pasted Layer [...the one with the girls] and press Add Layer Mask, and then click White (full opacity).
Now, after all of the above is done, click on the Paintbrush, and start colouring the parts you don't need.
When you are ready, and since I don't know how to use it well to save the image, I press prt sc [...the print screen button] and open Paint [...the normal one]. Press Ctrl+V and delete the bits you don't need. When you are ready from there, save it and then make it of the correct measurements over Picnik.
TPBM is now confused >.<
