I'm having issues with some georeferenced images in QGIS 2.10.1-Pisa.
I generally georeference PDF's of new land subdivisions over aerial photos to get the layout of the new subdivision, generally it works fine. Occasionally I go through the process of georeferencing the image and when finished the overlay doesn't show up on the map area.
When I look at the layer property the overlay shows as a thumbnail but not on the screen.
All that shows on the screen are the little red dots indicating the reference points I use to georeference the overlay so I assume the CRS settings are correct as the dots appear in the right places.
I have tried most settings that I can think of however I can't get the image to appear.
