How to display all of my pictures

[brittle757]

I'm having trouble displaying all of my pictures on my asus tablet, when I go to the gallery it only displays some of the pictures, even when I go into the album, I'm sure it's something simple but I'm a primary apple user so I'm inexperienced with android devices to say the least
