Just pick "dPhotos slideshow" from your folder's or jpeg file's context menu and the show is ready.
No configuration is required. The program uses few, easy to learn shortcuts and mouse gestures to navigate through the slideshow. It integrates With Picasa. You can add its button to Picasa's custom toolbar and enjoy new kind of slideshows in Google's application.
There are lots of software to manage your photos and many of them are very good but none of them is as easy to use as dPhotos. Just one click and slideshow is ready even if the photos are on your camera's memory card.
