What functionality does the Image Viewer Options provide?

The Image Viewer Options provide functionality that allows for interactive document markup. This feature is particularly useful for users who need to annotate, highlight, or make notes directly on the document being viewed. By enabling interactive markup, users can engage more effectively with the content, making it easier to provide feedback or emphasize specific information, which enhances collaboration and understanding.

The other options, while they may describe useful features, do not accurately represent the primary function of the Image Viewer Options. The ability to show thumbnails of all pages might be a separate feature that aids in navigation but is not the core functionality of image viewing. Similarly, translation tools and access controls relate to document handling and security but are not encompassed within the interactive capabilities of the Image Viewer Options. Thus, the primary value of this functionality lies in its ability to allow users to interactively mark up documents.
