There are a few ways to overlay pictures in Photoshop. One way is to use the “overlay” command. This command creates a layer that contains the picture you want to overlay. You can then use the “select” command to select the picture you want to overlay. The “overlay” command also allows you to add text to the picture. You can use the “text” command to write text on top of the picture. The “text"command also allows you to change the color of the text.
