Could you show me a picture view of my brake component

What is your question?

Could you please show me a picture of my break pads and the way I need to have it on?. Is there a right way my pads are installed because of the metal tabs that's on the ends of the pads?. My brother in-law took it apart and maybe one of the tabs were installed the wrong way,could I be right? If so,please show me the right way. Thank you so much.
