Picasa is a way to import, organize, and show photos.  It’s free, easy, and graphically looks great.  You can decrease  or increase the size of the thumbnails.  It will also organize by date. You can edit photos using effects, or undo crops at any time. You can always have the original picture.  You can make a slide show with your picture or send it by email.  It allows you to make a gift CD to send to family and friends.
