Why do my gallery photos disappear?

[Android Central Question]

I have a Samsung Galaxy s6 and it suddenly occurred that when I swipe through my photos, they disappear -
meaning the box turns white in the gallery and the photo is black when I click on the white box. This also occurs when I click on the photo to enhance it or make any kind of adjustment to it. How can i fix this problem?

Use My Files. Go to /sdcard/DCIM/Camera and see if there are any picture files in there. If there are, click on one. If it shows up, install Google Photos and use that instead of Gallery. (Some versions of Gallery in Samsung phones just don't work.)
