What does the "no thumbnail" error mean? I am able to take photos with my tablet, but when I try to view them I get a blank screen with the message "no thumbnail". I never had this problem before. I can see older pictures with no problems but I can't save any pictures any more. Please help.
This might be cause of low space in memory. This restricts your photo viewer app to make a thumb nail.

Thumb nail is a quick show sample of your original photo.
