Facebook | Picasa - Upload pictures in just one step. Brilliant.

For several years, I've been a user and a big fan of Picasa, a free
photo organizational tool from Google. I take thousands of pictures a
month, so keeping track of them, editing them, and sharing them is
tricky. Picasa works very well at helping with all of them. I just
discovered that there is a Picasa plug-in available for uploading
pictures to Facebook, another service I use frequently.

* Add the following plug-in:

* Select the photos you want to upload.
* Click the Facebook button
* Log in.
* Done!

Very nice.
