HI @iangilman - thanks for getting back to me. I cloned into that project and didn't have much success getting it to do what I was hoping it would do. The reason I'd like OSD to be able to do this is that I'm dealing with a programatically determined subset of 1.3 million jp2 images being served by an iipsrv - from 2 to 900 images. I get that a JS carousel could be effective for other images but haven't been able to find an effective solution for interacting with my servers and image types as they stand. I can't change either of these things as there are other parts of the project that depend on them.
