Well there is a better way...
The first thing you want to do is click on the Show Library icon (the icon is on the left side of the screen and third from the bottom.
Then select the file you want to use and click on it to load it into the Draw Area.
Now you can see the image and your drawing area at the same time while you work.
You can also resize each window to suit your needs.
So if you didn't know this, then give it a try!
