Querying A Database Through An Image

I'm building a path making tool, that is i have a network of paths for a park and each section of the path is its own image.

What i need to do is, when a certain piece of the path is clicked, it querys my path database and returns the information for that section of the path to a table.

Im designing in ASP VBscript and database is connected n all but im a beginner, is it feasable?

As well as this i need to be able to add to the table each time a piece of path is clicked, and also take away, like a stack.

AND aswell as this i need a seperate table which adds up the length of all the paths selected (length is in the database).
