Help New photos will not display in Picture Gallery

[PenguinFodder]

None of my newer photos from about two weeks ago onwards will display in the Picture Gallery app... which is funny, because until yesterday, they used to. They appear on my SD card, and they load fine with the phone plugged into the computer, but when I try to view them on the phone, I get a black screen before getting kicked out. I have already rebooted the phone.

It will not let me download that specific one, for whatever reason, so I downloaded another similar one. Nothing changed, though.

Also tried clearing out the cache data, which also didn't work.
