Did you try restarting the laptop? (turning it off and back on). Also, are these photos on the laptop itself, on the internet or on an external device? And what is the message you get when you try to open them or is it a blank/black image? Additionally, what file type are they? (jpg, bmp, gif, etc?) Lastly how are you trying to open them, with what program?
A little more information is needed.
