Instagram is a great way to interact with a wide variety of people and make extra money. Whether you want to engage with locals, fans of your favorite brand, or just want to show off some pretty sights, there's no shortage of ways to connect. For example, companies can run photo zoom contests or even showcase their hometowns in the grand scheme of things.

While you can't upload a full-size picture from your phone, you can use the Zoom feature to review a friend or colleague's picture. This feature is especially useful when you are unsure whether you are making the right decision or not when it comes to a potential romantic partner.
