Who maintains the Zoomifyed imagery after the initial design process is complete?

In actuality, no maintenance work needs to be performed on the completed collection of graphics unless changes are made to the graphic which will require that the process be repeated again in the future...scanning, splicing and Zoomifying the newly-modified graphic a second time. Repeating the Zoomifyed image creation process could be completed by either our clients, mapformation or any other third party, at the discretion of our clients.
