Why are images included in the Weekly Online Activity view?

Community Champion

The inclusion of images seems unnecessary as images are embedded on pages, assignment instructions, etc. If a student views a page they are also viewing the image that is embedded on the page. 

While I do not use many graphics I imagine others use ornamental icons or images.  Do all these then appear on this report? If so, doesn't that decrease usability? 

Perhaps I am missing a meaningful use case.
