Changing images using a timer?

Hi guys I was wondering what settings I should use so I can have around 8 different images come on the app screen with a set time between each image. I've tried different things but the app stops after the 2nd image. I can't see what i'm doing wrong!

It uses timers to control the animation speed and direction. Feel free to dig through it and use it for whatever you want.
Hope it helps!
