From the rulebook:
http://www.autopuzzles.com/forum/index.php?topic=6857.0The following picture modifications are not OK, and are considered by consensus to be unacceptable and unsportsmanlike.
1. Replace design elements from one vehicle with those of another (wheels, grille, etc.)
2. Photoshop modifications that change the basic configuration of a car (change a coupe to a roadster; make a Tyrelll P34 a four-wheeled car, etc).
3. Photoshop modifications that place a vehicle in an incorrect time or place.
4. Reversing a picture to make an LHD vehicle appear RHD, or vice-versa
As the poster in this case wasn't trying to pass the car off as being driven from the 'wrong' side (in my opinion) I suspect faska is correct.
Nevertheless, duty compels me to remind pftnbr to read the rules, and comply with same.
