The CrossSlide plugin, by Tobia Conforto, makes it possible to not just fade images in and out, but to also animate panning and zooming. This plugin is ideal if you have a variety of different image sizes. For best results, the only requirement is that all images are at least as large as the slideshow viewing area. Images larger than the slideshow viewing area will be cropped. For example, if the slideshow is 600 pixels wide by 400 pixels tall, then all images used in the slideshow should be at least 600 pixels wide and 400 pixels tall.
With JavaScript disabled, the CrossSlide plugin displays whatever content you've placed into the slideshow as a placeholder. This could be a single image, or it could be an image accompanied by text, or any other sort of HTML content you'd like. The plugin will then remove this placeholder content when the page loads and replace it with the slideshow.
It is possible to provide buttons that allow site visitors to stop and restart the slideshow...
