Whenever a nokia Symbian S40 series phone clicks a picture, it is initially store in an nrw file (which is like a RAW image format for these phones). Ideally, the phone's image converter runs in the background to convert these images to JPG. Your best bet would be to turn your phone off and on, so that it gets converted the next time you switch it on.

Download this codec, which should fix it for you:
