Do you need to copy an image into a new Photoshop file?
Good news. Copy the item you want to paste into Photoshop. Open Photoshop and select File > New (or press Ctrl-N) to start the process of creating a new file. Photoshop is smart enough to automatically analyze the contents of your clipboard and set the default size, resolution, and color model of the new image file to the exact specifications of the image you are importing. These dimensions will appear in a dialog box on your screen. You can accept Photoshop’s default specs or enter your own. When you have the specs you want, click OK and paste your copied image into the new file.
