Host.123Flickr comes from the makers of similarly monikered 123Flicker and it offers the same sort of service.
Namely, you can create slideshows from your Flickr photos. With Host.123 all your photo galleries are used to create several slideshows (123Flickr only takes your most recent entries). To make use of its features, copy your main photo url and paste it into Host.123Flickr’s designated bar. Click the generate button for slideshows. The interface is clean and simple with Flash execution. Click on the thumbnails to see the next image. An embed code function for exported your gallery elsewhere is soon to come.
