These apps are optimized for the larger screens of tablets and have either just hit the Android Market, or will be released this summer
First shown at SXSW earlier this year, LightBox is a photo app coming this summer for Android tablets and phones; it will be followed later by an Apple iOS version. LightBox enables a social photo gallery by providing a photo roll that syncs with the Web; your photos are shown as a feed, and there are hooks directly in Facebook, too. The app also provides an alternative way of viewing and perusing your photos on your device. It is currently in a private beta.
