Picking your brain for Charity! Is this possible on a website

Bonjour!

So I have a very unusual yet exciting, and possible quite challenging request for all ye on Creative Cow. I am building a website for which I need a versataile peice of coding.

I want something not too different from google maps. With the ability for members to change the images that make up the map.

Does anyone have any knowlege of any software/code that would be a good starting point.

p.s Please excuse my ignorance towards webdesign. I am an artworker by trade and don't have too much knowledge of website building. I have coders at hand, but they need somewhere to start...they aren't programmers!

I have found this, but not sure if I would be scammed for my money, or whether it is actually what I need.

Your Help would be very much appreciated and is going towards a good cause. If you have helped me I will even put your name in the credits!

Regards,

Josh

thanks for you reply.

Sorry, I will try to explain better. That I-mapper program allows you to create a map out of one image, What i would like to do is create a map of multiple images. That is constantly expandable. I guess like a grid system. If this is anyway possible.
