Fotoviewr is a new (free) Web-based service to turn your Flickr (or SmugMug) photos into a cooler interactive slideshow for your friends and family. You could easily get a slideshow set up in less than a minute with Fotoviewr – just plug in a Flickr/SmugMug username, then select the photoset you want to display and third, the type of slideshow you want. Fotoviewr has 6 different types of slideshows from a carousel to a wall of photos to a pile of photos on the floor.
While I love Flickr for its clean website, I find it a bit slow. Fotoviewr speeds things up by preloading the photos and making it significantly faster to browse. Fotoviewr has also built an application for you Facebook junkies.
