As you can see in the sample apps, there has to be longitudes and latitudes values to plot a location and a dynamic image that is available as google api. I am not sure if the same is avalable with the website you provided. If not, you might not be able to do it that way. Try to contact them for the same and see if they can help with data and keys.
