> Hello everyone. The latest map for my atoll was 1986 (paper only 1:25,000), but I have a high res jpg which I've uploaded into QGIS 2.0 OK. Map was in UTM zone 4. I have also successfully uploaded a GPX file of waypoints that I'd like to display on the map. At the moment I can still move the jpg around in the map window. What do I need to do to fix the map in place and how can I relate the waypoints (WGS84) to the map. Is there a way to select a lat/long on the map and then the same waypoint in my GPX file, thus linki9ng the two things? Thanks Michael

You're slightly confused. The map will always be pan enabled, you aren't
actually moving the image, you're changing the center point of your
view. What you want to do is enable projection on the fly, making sure
that the projection definition for your jpg is correct to begin with.
Once you do that your GPX points will overlay properly.
