Why aren't my photos showing up in my gallery?

[AC Question]

I took some photos this afternoon, and went to see them in my gallery....but they're not showing up. The last set I took a few days ago is there...just not the ones I took today?

Welcome to Android Central! Is the Camera app set to save photos to Internal Storage or the microSD card? If the latter, the card might be failing.
