SlideFlickr is a service that enables you to embed your Flickr slideshow, just about anywhere.
This new service is extremely easy to use. Enter the URL, username, or group for the Flickr slideshow you want, and the embed code is provided for you. Advanced options allow you to customize the widget's size. The Flickr slideshow operates just as it would on Flickr's site, letting viewers flip through photos and choose the slideshow's speed. SlideFlickr works in Internet Explorer, Firefox and Opera, and can be embedded in your MySpace, hi5 or Piczo profiles, or your blog or website.
Other slideshows include RockYou, Photobucket, and Slide, among many others. There is also a Flickr application now available for Facebook.
