Shacked Software has released an update to Flickpad HD, its iPad photo-browsing app for Facebook and Flickr. The new version now includes direct support for The Commons, Flickr’s collection of public photography archives and adds a Flickpad Tour on initial startup to help familiarize new users with the application. Users can also now choose from five different backgrounds and easily toggle between showing Facebook or Flickr photos. Additional improvements include an integrated crash reporter, several UI enhancements and bug fixes and a new app icon. Flickpad HD requires an iPad running iOS 4.0 or later and is available from the App Store for $3.
