Instagram is holding onto its place as the darling of the mobile photo sharing world.

The future is looking extremely bright for the 13-month-old, 7-man company: Goldman Sachs recently designated it as a potential IPO candidate and founder Kevin Systrom expects the membership base to double once the Android version arrives.

Google’s new Photovine mobile photo sharing app for iOS is now out of private beta and open to public signups. Here’s how the iTunes download page describes it:

Photovine is a fun way to learn more about your friends, meet new people, and share your world like never before. It all starts with what we call a photovine: a group of photos around a single, shared caption. Start a new vine with a photo and caption of your own or add your photo/take on someone else’s vine.

It has a long ways to go before it can catch Instagram, which is currently the 800-pound gorilla in this space. Instagram has already passed 7 million registered users, who have uploaded more than 700 million photos. Google has a pretty big reach though, so products launched by the company can get really big, really fast — just look at Google+.
