The type specifies the type of component, as in what the component literally is, Image, Text, etc etc. The correct setting there would probably be grid or image depending on how you've attempted to this this up. From what I can tell, you've already tried to set up a grid, so what you're aiming for is probably an image? If you've done lunatic items, you shouldn't have to manually define actor 1 image, actor 2 image, etc since it should render one image for each set of data that exists.
The type "face" from the sideview template draws on the face picture you've set in the engine for the character. I would suggest just directly taking that config if you're fine with that, but if you want to do custom images, take a look at how the busts in the main menu is handled and try that method with images instead.
