<human>:  How do I hang pictures on a wall?
<bot>: To hang pictures on a wall, you will need some basic tools such as a hammer, a drill, screws, and wall hooks. First, measure the size and position of the picture you are going to hang, and use a pencil or marker to make a light mark on the wall. Then, use a drill to make holes for the screws and hammer the screws into the wall. Next, fasten the wall hook onto the screws and place the picture onto the hook. Finally, adjust the picture to make sure it is level and securely in place.
