Here is a demo of what a slideshow might look like
To get the best out of it need to be careful about image sizes
A description of each image can be shown – with fade in
Photos are assigned to a “gallery”, each gallery can have an “unlimited” number of photos. Slideshow speed is configurable. Size of the images to be displayed is defined in the “gallery” settings, it doesn’t change for each photo – otherwise the page would be constantly moving. This demo has the image size set to 700×700.
