Depends on what program you are using Elite Four Lucian, but if you open the user bar on your program and then either copy and paste the sprite onto the canvas, or if you've got the sprite saved on your computer you can File > Place (Photoshop).
If you have Photoshop I can walk you through step by step, but it'd help to at least know what program you have, and then take it from there.
