Social networking site, Facebook, in the midst of their IPO roadshow, have just acquired Lightbox. Lightbox is a predominantly Android-based photo sharing startup, which shares quite a lot with the recently-scooped-up Instagram.

Lightbox will be closed by Facebook, and the company will most likely use staff developers for Android-based development. No terms of the deal have been announced. Just after the announcement, Lightbox stopped accepting new users, with existing users having until June 15 to conclude business and download all remaining photos from the service.

Existing photos will not be transferred to Facebook, which is a bummer. Lightbox's founders are quite happy with the deal, where they've said they are:

Happy to announce that the Lightbox team is joining Facebook, where we'll have the opportunity to build amazing products for Facebook's 500+ million mobile users.

On a good note, no layoffs have been announced, nor are they expected.
