[sean lee] " have no idea how to insert an image around the person."
You don't insert an image around the person, you essentially cut the person out of the existing frame, then put an image behind the person.
First, you create freeze frame of the person.
Then, you rotoscope around the person (best done with Motion, Combustion, AE, Photoshop, etc.) - i.e. draw a freeform matte around the person, thus turning everything outside the matte transparent.
Then you put the person on V2 above a background, which can be anything you want; video, text, animation, etc.
