Picasa is a free photo organizer desktop app from Google. It is very easy to process your photos with Lo-Fi when you are using Picasa. Here are the instructions on how to do this.

1. Run Lo-Fi and Picasa.

2. Use Picasa to select the photos you want to process in Lo-Fi. Use Cmd-Click (Ctrl-Click on Windows) to select multiple photos.

3. Drag these photos and drop them into Lo-Fi. You can now use Lo-Fi to apply your favorite retro effects.

4. When you are done, you can save to disk or upload to Facebook or Flickr. If you choose to save to disk, choose the Picasa preset option. Then click Save.

Picasa will typically watch the folder and automatically import the new photos that you saved. These new photos will appear at the bottom of your folder view.

That's all there is to it. Enjoy Lo-Fi!
