camera not taking pictures

[ethan]

For some reason my camera has stopped taking pictures. I'll snap a pic, then when i click the thumbnail to view it, it shows me an old picture from some time ago. also, im not sure if this is related, but all the thumbnails in the gallery have turned into weird symbols but when you click on them it shows the picture
