I'm designing a website for a competition using XWD6 and the legal team involved are talking about making it something like an online 'Spot the Ball' competition as opposed to an entrant answering questions.

Has anyone ever done anything like this? I'm not sure where to start if they insist on heading down this route.

I'm not a programmer, just a simple web designer and it's my family and I who are offering the competition.

For those who don't know what Spot the Ball is, this is from wiki:

A spot the ball competition is a traditional newspaper promotion where the player has to guess the position of a ball which has been removed from a photograph of a ball sport, especially association football. The position of the ball must be deduced from the relative positions of the sportsmen shown in the photograph, the directions in which they are looking, etc.


Any and all sugggestions appreciated and if you've ran an online competition before I'd be interested to know what you did. Thanks!
