At the moment, our standalone Image Reorderer example, our documentation, and the default API all suggest that there's a required contract for using prefix:name:suffix-type IDs in the old RSF/Image Gallery style.
This is a complex solution for newcomers, and is entirely unnecessary with the modern Reorderer API. We should do the following:
1. Create a new standalone demo that takes a lighter approach to markup, without imposing an id-based contract
2. Improve the documentation to reflect this
3. Delete the obsolete afterMove Callback page located here: http://wiki.fluidproject.org/display/fluid/afterMove+Callback
