the other way is to hit the create tab on the top of the window. Look in the tutorial and see how its done. You do need a steady hand with the mouse or better still get a graphics tablet. as you follow the instructions write down the steps. or open them in another window.
open the SSD window. next click n the icon that looks like a brush on the left hand side. This will bring up a window with a santa in it.
right click on the border surrounding the santa and a tab opens click on "IMPORT IMAGE" you can now upload your jpg image. hope this will help you.
