3. Select the image to be used - browse your computer for your image by clicking 'Browse'

4. Adjust the size of your image - your image will come in with green control points that can be manipulated to change the scale and orientation of your image. The dialogue box must be open to manipulate the image location.

5. Adjust the opacity - the opacity slider is also helpful in aligning the image

Additional tips:
