Yar there is a world of difference between the pictures taken in Pakistan, pictures taken in UK and pics taken in USA.
The wood texture, paint, background items, condition (dust etc), all are apparent. The picture had light colored wood on it, and had a UKish texture. So I searched for it and found a picture on google images. Its really easy though, and takes only 2 or 3 minutes. But if everyone started doing that, it would take 3 or 4 hours just to go over 2 day old threads in a single section like Computers and Hardware.
Also, the reviewers have a different type of angle to their pictures. They hold the camera in a certain position. Normal people don't do that.
