Lightbox announced the deal in a blog post. However, the company also made it clear that Facebook was not acquiring the company or the photos that users had stored on the Lightbox website, just the developer team.

Lightbox also provided a download link so that users could export their photos, if they so chose. Users will only be able to use Lightbox.com until June 15. The company is not accepting new signups.

Lightbox is actually quite similar to Instagram, which Facebook bought for $1 billion at the beginning of April. (Instagram was originally only an app for Apple iOS devices, but later released an Android version that nabbed 1 million downloads almost immediately.

Touting itself as "the connected camera," Lightbox allows people to use their Android phone to take photos, apply filters, geolocate the photo, and identify the place where it was taken, as well as post to Twitter and Facebook, naturally. So far, however, Lightbox only runs in Android and HTML5 versions, meaning that the developers may be asked to beef up Facebook's Android application, which was recently boosted with larger photos.
