How to Magic the inside of an object along with the outside silhouette

[Stargoop]

I am attempting to copy an image of a football player (with a solid white backround) to place on a different backround. Even when I  use a transparent backround the Magic Wand cannot see the area between his arm (which rests on his leg) and the shirt/leg. Photoshop is able to do it when I Quick Select Subject but Paint.net only reads the outside of the image. Is there a solution to this?

After selecting the magic wand tool:

1. Set flood mode to global
2. Click the white area
3. Adjust the tolerance until only the white area is selected
4. Press the Del key on your keyboard (not the backspace key)

A checkerboard indicates transparency.  Be sure to save in a format that supports transparency: PNG, GIF, etc.  (JPG does NOT support transparency)
