iiif.io The International Image Interoperability Framework (IIIF) maintains two standards. The IIIF Image API makes it possible to store an image once and serve it as needed in small pieces of various resolutions, sizes, and orientations. The IIIF Presentation API defines an interoperable way to describe a canvas (such as a page of a manuscript) in the context of a larger object (such as page sequence and orientation) and the components (such as images and annotations) that describe it.
projectmirador.org Mirador 2.0 offers a very powerful environment for viewing and comparing images described according to the IIIF standards. The project website offers a demo.
