Have the user select a route and have the image of the map appear

I am working on a new website for a non for profit. I am stuck in trying to get the route people chose and displaying the map for the route. I was thinking in putting the route map in the Trigger email, but I know that is not possible at the moment. I was then thinking about adding the route picture along with a link to print the route map in a lightbox. The lightbox will appear when the user finished submitting their information. In the lightbox I wanted the route map to appear for the user to print it or save it to their computer. I need help in setting up around 250 maps into a database and pulling the picture and the user selection to portray the map image for the user to save.
