Hi michell610. Welcome to the forums.
Photoshop provides various ways to get rid of a background color like that. I'm no expert, but one thing I do is firstly to click the layers palette and change the name of the image layer from the default "background" to anything else. Then click the magic wand tool, set a low tolerance in the settings at the top (like 1). If the white areas are not all contiguous, deselect the "contiguous" box at the top. Then click on the white area with the wand and it will be selected. If you hit Delete on the keyboard, the white background will disappear.
