Picture Frame is a Widgets software developed by Yahoo!. After our trial and test, the software is proved to be official, secure and free. Here is the official description for Picture Frame:

BS Editor: What started out as a Widget to show you your local pictures as a slide show in a Frame has become a complete Flickr and Yahoo! Photos upload and management tool.

With this latest version you can upload images or Folders of images to your Flickr or Yahoo! Photos account, change names, descriptions, tags, Privacy options... you can even blog directly from the Widget.

Part of the Yahoo! Widgets 4 installation, but offered here in the event you've lost the Widget.
