If you want to add a photo layer in Photoshop, there are a few things you need to know. First, open Photoshop and create a new document. Next, select the Layer button in the toolbar and choose New Layer from the menu. Now, click on the Add a Photo Layer button in the Layers panel and select your photo from your computer. You can also use the Browse button to find your photo on your hard drive. Once you’ve selected your photo, Photoshop will open it in its own window and place it on top of all of the other layers in your document. To change the size or position of your photo layer, just click on it with your mouse cursor and drag it around the screen. To delete a photo layer, just click on it with your mouse cursor and press Delete (or use the keyboard shortcut Command-Delete). ..
