seeking feedback from users of the Picasa desktop client

I made a picasa button for uploading photos to OurDoings, but since I'm not a picasa user myself, my testing is limited. Can anybody test how easy it is to find, use and install the button, if you're already managing your photos with the picasa desktop client? Just go to the front page, and comment here if you get stuck or notice anything else that merits feedback. http://ourdoings.com/
