A very simple gallery setup (click on the images to the right to enlarge the settings) that would make a great first impression on your websites landing page accompanied with text. Images are shown one at a time and automatically elegantly fade from one to another. They're set to keep their original aspect ratio, without cropping. Notice how the slideshow has been set to pause on hover.
How you then choose for the images to scroll, whether the slideshow starts automatically, or has navigational arrows is entirely down to you... the possiblities are endless!
