Doesn't look too complicated. take an image on a white background, crop out white, superimpose image over Google-searched background and profit. Nothing too big.

The background is a google searched are image, you are correct. And I was only experimenting, I built a green screen and took some images using the hide node and everything. If you notice, it's missing a shoulder. I should fix.
Tip: Mspaint and the wand tool. Take the picture in a fullwhite backround. Then you can remove the white and make it transparent, from there it can be put anywhere.
