I'm trying to set up an embeddable slideshow that I can embed on several websites. Flickr seemed to work well, but they don't give you much in terms of configuration, or options for the embedded show. For example, I get complaints "it goes by too fast" etc..

Are there any hosted galleries which will give me (or the user) a lot of control when viewing an embeddable slideshow?

All I know of is Picasa and Flickr, and they aren't helping much
