Familiar keeps growing, tops 47M photos displayed in Nov.

Photo sharing may be one of the most hyped parts of the consumer Internet world, tracing back to Facebook’s big buy of Instagram.

But even so, people still love shooting and sharing photos from all sorts of gadgets. And that trend is playing right into the hands of Familiar, a Seattle startup led by former iLike developers Marcus Womack, Mike Bohlander, Ray Fortna and Josh Hepfer. We wrote about Familiar back in September after it reeled in $1.3 million from Greylock Partners, Redpoint Ventures, Index Ventures, Acequia Capital, Allen & Company and angel investors Ali and Hadi Partovi.

Back then, the company was displaying about 20 million photos per month. But that number has soared to some 47 million photos during November.  Since launching 12 months ago, a whopping 200 million photos have been displayed via the service. It expects to top 1 billion photos displayed in 2013.

Familiar makes it dead simple to share photos with groups of people, essentially creating a digital slide show on a friend or family member’s computer, tablet or phone. That resolves the problem of emailing or texting photos or uploading them to a photo sharing site.

Today, the company also announced a new feature that allows users to send wallpaper photos to friends and family. Co-founder Marcus Womack explains the service in this blog post:

“Picture a scenario on Christmas morning: The kids are tearing open presents from Nana. Though Nana can’t be with the family during the holidays, she’s able to see on her wallpaper – in real time – a photo of the kids’ excitement over their presents – all before the wrapping paper is cleaned up. Photos display immediately upon accepting an invitation, and subsequent photos are displayed instantly. You can even send to the wallpaper of multiple family members at once, and they’ll all be set simultaneously. That means you can update the wallpaper on Grandma’s desktop or Uncle Ron’s tablet just by uploading an image.”
