Photo taken unable to be saved in memory card

Hi, after i take a photo with my Sony DSC-W350, the photo is not saved into the memory card. I can preview the old photos in the memory card. There are still lots of space in the memory card

Some SD cards have a "lock<>unlock" slider, basically a write-protection feature to prevent existing pics being accidentally deleted. But it also prevents new pics being written to the card. Take out the card and make sure the little slider is in the "unlock" position.
