HI, Im new here, thans in advance for your help. I have about 4500 photos stored and sorted on Nikon's "PictureProject" sofrware--it came with my camera. Why, suddenly, are all the images replaced with a gray "Jpeg" ikon? there is an exception which I hope will be telling. The few photos Ive collected, taken by my daughter on HER camera, are all visible as before. Strange? thank yu for helping me. sincerely, Chrisman
