The primary reason you should graphically (or not so graphically if using steganographic tags) tag your photos is to add some identifying mark on them, or even just add context. With iWatermark+ ($3.99) you can add a copyright, a custom icon, a logo, or even embed hidden steganographic data in your photos. You could also simply share your email, a uniform resource locator, or QR Codes (with links to either) from within your images. The latest version also allows you to watermark your videos.
