Interface And Graphics :: VB Map Application - Enable Users To Select A Map Zone Of A City Centre?

I am developing an application for an emergency services organisation using VB 2008 that will enable users to select a map zone of a city centre and plot icons onto it, then save/export the layered map with icons as an image.My problem at the moment is that I am struggling developing the point where the user imports in the icon (for example, a flame icon where a fire started) and drags it around the map within the picture box to the required area.I want them to be able to select their desired icon from a series of commandbuttons and for the icon to 'appear' on the picturebox and be enabled to be dragged around and dropped as required. The organisation already has such a thing working in Microsoft Word (!) and that uses the ActiveDocument.Shape.LoadImage function on a pushbutton to import the icon and then it is placed on the map as required, but this is really unreliable for them.I dont even know if you can layer images onto an existin picturebox within an application in this way and then export as a flat image.
