BridgeURL is a simple tool for grouping URLs together into a "slideshow" of websites. Visiting one BridgeURL link allows you or your link recipient to page through multiple sites, browse them, and break out of the slideshow into individual pages.
Visit BridgeURL, plug in the URLs you want to use for your web site slideshow, create the link, and then share it. Anyone who visits the link will see the website with two navigation panels on either side, enabling them to page forward and backward through the slide and break out of the slide show.
BridgeURL is a free service and requires no registration.
