Whare is a Dynamic Image tutorial to be found

I am looking for a guide or tutorial (preferably not OO) to help me do the following. A client views a map of a country and clicks on his location. Location stored on database. A visitor enters makes a selection (e.g. Hotels) then views a map of the country modified to reflect those locations (clickable hot spots with mouse over information highlighted) that meet his needs. This would mean either generating a map for every request or somehow overlaying the country image. There would appear to be many tutorials but I would appreciate a pointer to one which would be applicable to my needs.
