Photoshop is a powerful image editor that can be used to split an image into two or more parts. This can be done by selecting the part of the image you want to split and then pressing the CTRL+SHIFT+A key combination. Photoshop will then start splitting the image into the selected parts. If you want to keep all of the original images in one part of the split image, you can press CTRL+C to copy all of the images in that part and then press CTRL+V to paste them into another part of the split image.
