Check out the documentation for image(). You can use fourth and fifth arguments to change the display size of the image. But keep in mind that since it's a raster image, changing the size will potentially distort the image. If you want to make sure the image is not distorted, you can check the dimensions of the original image, and multiply both width and height by the same amount.

For example, if the original image was 200 pixels wide by 500 pixels tall, you could scale the image without distortion to 400,1000, but changing width and height by different amounts (for example to 400,500) would distort the image.

Oh, one other things. I mentioned that you should comment out lines 20 and 29. That is true, but will cause another problem – perhaps that problem is why you did things this way to begin. The problem has to do with scope, and the solution is to use global. Like this:

    # put these lines in the setup() block:
    global img
    img = loadImage("some-image.jpg")

    # put these lines in the draw() block:
    global img
    image(img,0,0)

We'll talk about this more on Weds.
