What is the difference between FSI Viewer, FSI Showcase and FSI Pages?

FSI Viewer offers the core functionality for communication with the Imaging Server and the user interface for interaction. While FSI Viewer alone is capable of displaying zoomable images, FSI Pages and FSI Showcase are both add-ons to FSI Viewer, which extend the functionality of FSI Viewer and can be purchased separately.

FSI Showcase extends FSI Viewer adding the possibility of displaying multiple images within one FSI instance.
FSI Pages adds functionality for online brochures, catalogs and shop integration.
