Showing GPS location on a JPG map?
<p>I have a georeferenced image that's really an image of a map.  I know the latitude and longitude of several points on the image and I'm trying to figure out how to display my location on the image.  Similar to how Google Maps works, but instead of using Google Maps I'd like to use the map I have a JPG of.</p>

<p>Any ideas on where to start?</p>
