And here's the back of the house.  You may notice much more detail in this bigger picture.  Only those who have some interest in a particular product are likely to arrive at the full sized picture--so the written description can be a lot more detailed, since many will be interested enough to read it.  Notice how much empty space there is under this short written piece--room for a lot more print to explain details of the product to those who have self selected themselves as interested by double-clicking on that particular thumb nail on the first page.
