I tried to use the georeferencer in the new Qgis 2 64 bits for windows. I tried with the standallone installer and with the OSgeo4w installer. The problem is when I load the raster that I want to georeference, all I get is a gray square with a bunch of blurred colors at the top. I tried to use the georeferencer in Vista 64 (8gb of RAM) and in win 7 64 (16 gb of RAM). Also running Qgis as an administrator did not solve the problem. I used the same image in a 32 bit installation of Qgis 2 and I have not a problem loading it or working with it. I would appreciate any hint in what can I do to solve the issue

What type of a raster is it? You may want to read this question and answer first: Opening TIFF DEMs in QGIS – Get Spatial Sep 22 '13 at 21:25
The 64bit build is still experimental. Some things might not work 100% yet. – Nathan W Sep 22 '13 at 21:50
@get spatial I was trying to open a non georeferenced jpg image, not the ones mentioned in the link. I was trapped in the first step of the image georeferencing process. – Gerardo Jimenez Sep 22 '13 at 22:44

I had the same problem... it was because it was in JPG. I had a TIF image, but I wanted to test a thing and saved it as JPG... and I got exactly what's described.

After that, I tried to save it as a BMP, and the image format problem didn't occur again, could be the handling of the JPG format.

JPGs in the 64-bit version have a known issue: – underdark Nov 14 '13 at 16:52
@Simbamangu I appreciate the tip. Yes, changing the image format allows me to work with the georeferencer. I used bmp and png and seem to be working ok – Gerardo Jimenez Nov 14 '13 at 20:06
