Hi Rhcp214,
As initial troubleshooting step, I suggest that you follow the instruction that was provided by dissed. This option will remove the hidden attribute of the photos. If this issue persisted, please provide us the following information:
• File type of the photos from your cell phone.
• Does this issue occurs to all the photos in your Windows Live Photo Gallery?
• Were there any changes to the computer before this started to occur?
Thanks,
Windows Live Gerard G.
