If you are like me you use Picasa to manage your photos, but recognize that the editing options are very limited. You can easily add a button in Picasa that will allow you to edit the current picture in photoshop.
I took an existing button built for PhotoshopCS3 and updated it to work with this more contemporary version. It’s limited to working only on Windows.
This will open in Picasa (may prompt you to allow this) and add the button.
The original Photoshop button was created by Michael Herf.
