Cannot open jpg files in Preview? Error message "may be damaged or use a file format that preview does not recognize".
For some reason I cannot open jpg files from a co-worker who previosuly sent files without any problems. I just bought a MacBook Air with OS X Lion & Preview won't open the files. She sent the same files to another co-worker who opened without any issues? Help! Anyone have any suggestions after having the same or similar problem?
MacBook Air, Mac OS X (10.7.4)
