With Picasa for Mac installed, which is a freewareprogram from Google, you'll be able to import, edit, organize and share your pictures.

The first time that you use Picasa for Mac you'll get the possibility to search your Mac for pictures or you can select the folders containing pictures manually. Picasa's interface is not quiet as you're used to as a Mac user. If you have used iPhote before you will feel confertable right away with Picasa for Mac though. With all in place you can now easily produce slideshows, movies and collages from you digital photos.
