Preview pictures in Camera

[AC Question]

I have Samsung J 5. When I press preview pictures on Camera, it show all the pictures in my mobile such as recived by Whatsapp not just the pictures i took through the Camera. How to make it that when i press the preview picture, it shows only the pictures i took

Thanks

The app that is showing the preview, is it the camera app or your normal picture viewing app?
