One of the things that Popfly does well is take photos from one place (e.g. Flickr, Live Image Search, Facebook, Live Spaces) and display them in another (e.g. your blog) in pretty ways. Tim on our team created a really nice block called "MovingSlideShow" that takes simple photo display a step further: it pans around the photos, much the way Ken Burns (the director of the documentaries The Civil War and Baseball) did to make static photos from historical archives seem more alive.
So what does this mean to you? If you like what you see and want it on your own blog for your photos, just Tweak the mashup. From the Popfly Tweak screen you can change search terms or even go into the full editing mode to change data sources. For example, instead of just pulling photos from a Flickr search, I built a mashup that pulls photos from a Facebook photo gallery and a Flickr search as well. As my subject matter, I used Robert Scoble (a relatively safe subject since there is a substantial amount of content on the Internet by and about Robert) and the book "Naked Conversations." The result is actually a moving slideshow of some of Robert's more recent activities.
