Instagram enables you to view photos on the mobile app and the website, but only after you have registered for an account. If you're new to Instagram, the registration process can be confusing, particularly because it's different from many other social media websites in that you can't register on Instagram from its website.

Registering With Instagram

Unlike other social media sites, Instagram doesn't provide a registration option on its website. Instead, it requires you to download the app before you can create an account. The app is available for Apple, Windows and Android mobile devices. After you have registered using the app, you'll be able to log into the Web interface. As of January 2014, the site had not announced plans to add Web-based registration.
