Cutting Out V2
Have your image open. Now go to the Pen Tool.
Match your Pen Tool setting's so they match mine.
Zoom into your image, I zoomed in to 300%.
Start clicking around the site model's figure, you should see little dots following you..
Go all the way around until you reach your original starting point. When you've reached the starting point your dots should disappear and then look like the image below.
Right click near the selection and press 'Make Selection...'.
When this box appears, make sure your setting's match mine.
Your selection should now look like this.
Go to 'Select > Inverse', now your selection will hopefully look like the image below. Press the 'delete' key on your keyboard so the background disappears.
Here's my result.
