I have been trying to georeference in ArcGIS Pro to a jpeg. I have done this several times before, but this time, when I try to add the image to the map, I get the error message "failed to add data, unsupported data type". Strangely, I was also getting this message while trying to import a .TIF, but if I right clicked on the tiff or the jpg in the catalog and converted to TIFF or JPEG using "Export to Different Format" I could get the images to appear on the map. Now however, the georeference tool is greyed out and cannot be used. What am I doing wrong in terms of adding plain images to be georeferenced on the map?
