Why do pictures of Chess sets always show bad positions?

Just got an email from USCF proudly displaying the image of a wooden set with this image: 

What is the white Knight doing on d5? Is it white's move? Black?  If it was white's move, that means that black didn't take the knight enprise, if it was black's move, then white just placed the knight enprise. I looks like b4 was just played, then Nd5??

Not only in these pictures, but also in movies ... how hard is it to show a chess board without silly positions, or people playing chess "looking serious" about it that have no idea what they are doing.  You can't play chess in the park without holding/moving the pieces like a chess player, yet so many movies have shown people playing who obviously have never played chess, ever.
