Slideshow Widget is a Dashboard widget that displays a series of images that can be presentated as a presentation along with hyperlinks to specific Web pages.
Right-click (control click) the widget and select "Show package contents." Then double click the Photos folder and copy your own images here.
If you're a widget hacker, feel free to use this code as the basis for your own SlideShow! (A link back to this page on the back side of the widget would be appreciated if you do use this code. Thanks!)
