Android: If you're looking for a more versatile picture viewer than the default app that came with your Android phone, JustPictures is a lightning-fast and web-integrated photo viewer for Android phones.
If all JustPictures did was load photos in a quick manner with excellent response time and multitouch interaction it would be an excellent photo application worth the download. In additional to snappy local photo viewing, however, it integrates with popular web-based photo services like Flickr, SmugMug, Picasa Web Albums, and social sites like Facebook so you can not only browse the photos on your phone but also the galleries you have stashed about the web. The next time you pull your phone out and want to show a friend pictures from a Facebook album or your latest photography experiments on Flickr you'll have them right at hand.
JustPictures is a free application and works wherever Android does—though some of the advanced features like Live Wallpaper only work on Android 2.1 and above. Visit the official site at the link below or scan the QR code at right to download JustPictures to your Android phone.
