How to Undo Picasa
When you work with your photos with Picasa, Google's free photo management application, you might make a change to an image, and then realize you don't like the change and want to undo the action. For example, you might have cropped a photo, adjusted the contrast or applied a special effects filter that you now want to reverse. Picasa automatically creates a new copy of your photo when you edit it, and keeps the original file intact on your computer, so you can undo a save, as well as revert your image after multiple edits to how the image appeared originally.
