    ANY time you manipulate a jpg format picture you will loose quality. Thankfully Picasa keeps the original intact in a seperate folder for you.

    Even opening a jpg and and saving it again will cause quality loss.

    Any program you use to manipulate a jpeg will cause it to lose quality. If you decide to manipulate one, work from a copy and keep the original intact. That way if you make a mistake you still have the original to work from. If you're making a lot of changes rule of thumb is save often.(each save with a different filename) This way you can go back to an acceptable image and not have to start all over from scratch.

    A JPEG image is a compressed image, therefore it starts off with quality loss. Some image processors can retain the quality it does have better than others.
