As a user, when clicking on an image in Media Viewer I want to know in advance if it's going to trigger a download
Open, LowPublic



For most images, when you're in Media Viewer and click/zoom on them (with the magnifying glass cursor), you are sent to the URL of the asset (e.g. clicking on the image here sends you here However for certain images (.tiffs at least, maybe others), have different behavior. Instead of sending you to the asset URL, instead the browser triggers a download of the file.


  1. Go to
  2. Scroll to the History section and click on the second to last image (Map of the Pacific Ocean during European Exploration, circa 1754.)
  3. Click on the image again

You would navigate to the asset URL

Browser triggers download of asset

Provide some kind if indication, whether through use of a different cursor (although there aren't any obvious choices, perhaps .s-resize would be somewhat indicative of "download") or through a tooltip, that clicking the image will trigger a download

Probably the fake zoom feature should not be enabled on such images in the first place. There is already a download dialog which does not surprise users by transferring hundreds of megabytes, which is the typical size for a tiff.

I don't see this as a huge priority now, but something to keep in mind when we revamp MultimediaViewer for Structured Data anyway.

A more general approach would also be to not show zoom-in icon if on click there won’t be any enlargement from going to the asset URL, since I’d think that many users would find this confusing (and maybe even going against the spec? haven’t investigated it).
