Picapy is a Desktop App to manage your Picasa Web photos without opening a browser or installing Google’s Picasa Photo editor.
It works just like a file browser. Once logged in, you’re presented with a window displaying your Picasa Web albums. There you can add, edit or delete folders to your choosing. To edit/remove more than one folder use CTRL+Click.
