There are conceptual differences between WP and OSM, but the underlying 
problem stays the same. Choose one "prominent" photo representing the 
object. WP can do it, so I don't see a good reason why we can't.

But that doesn't really matter, that's what I wanted to point out with 
the Wikipedia comparison. Yes, there can only be one photo to represent 
the OSM object.

The image tag represents an image of the object, not necessarily the 
best possible image ever made.

No, if you tell me this, you could simply lie to me :-)

P.S: BTW: It doesn't really matter what you think about it! People will 
use image=xy anyway as they already do ;-)
