Mixed Media Labs, the developers of social photo sharing service Picplz, has just raised $5 million in new funding from Andreessen Horowitz. Marc Andreessen will be joining the startup&'s board of directors

Developed by Imeem execs Dalton Caldwell and Bryan Berg, Picplz aims to be a dead simple way for users to share the photos they take on the phone on the web. Pictures taken with picplz are synced to your profile on picplz.com and tagged with your location and place. And you can post directly from the app to Facebook, Twitter, and can also check-in to Foursquare when you take a picture. The app also allows you to follow other users&' photo streams, similar to the Twitter model.

The startup initially launched an Android app in May and then rolled out an iPhone version in August. Between the two apps, Picplz has seen over 100,000 downloads.

PicPlz most recently rolled out updated apps with the ability to add special affects to pictures, a new UI and improved photo upload speeds.

Caldwell notes that the funding will be used to expand the scope of what the startup is doing in terms of monetization and new products. It&'s unclear what the details are at the moment, but we&'ll keep you updated on any new developments.
