I've searched the help archives, but I guess I'm using the wrong key words.. I've got entire folders of pictures that are too dark, and they lighten beautifully in Picasa with just one slider, but my problem is just like Lightroom 2-it doesn't affect the original. I want to make the changes to the original and have it stick, not go away when I close Picasa. If I open Picasa back up, the changes are still made, but not while viewing the pics in Windoes Explorer. How can I make the changes permanent? Thanks.
