Several Picasa slideshows on Blogger at once?

I want to use small slideshows on the side of my Blogger blog. I have added one. It's not giving me the choice to select other albums for additional slideshows. Is it only possible to run a slideshow from one album at a time?





I'm adding these as Gadgets, on the side, not inserting into posts.





If it's possible, please tell me how to do it.





Thanks!
