LR v4: an import of select photos was performed and put into LR. Performed customized print option through lightroom of selected photos. Then tweeked some photos creatively in photoshop (stand alone, not performed via LR). Saved images in edited format (jPEG from CR2). Went to LR to import these photos and LR did not recognize or find them (did recognize the photo's corresponding RAW file)....closed LR and restarted. Still no recognition.
