Ahhh. Luckily, her photo should be verrry easy, since the background is solid. Great one to start with to get the hang of it. (On the image window: Layer > Transparency > Add Alpha Channel, then use the eraser on a solid round to get rid of the bulk of the gray. Then I usually pick a smaller one, refine the edges around the person some, grab a smaller one again, zoom about 400% and start going right up against the form, then a suuuper tiny one for all the itty bits that got missed):D Either way, that tutorial should definitely help you get a good idea of how it's done.
