Not all jpg's on UHH need a download in order to view exif. See my topic:

In using an exif viewer extension for Chrome browser, I found the data for that shot is viewable. See the tiny icon in upper left corner of the photo.

For photos where exif is not viewable on the "thumbnail," but when a download link is available, click the link and then use an extension for your favorite browser. That's the easiest way, and doesn't require downloading the photo to your computer.

Otherwise, as mentioned already, there are websites for exif viewing. Here's one:

Or download the photo to your computer and open in one of several ways: right-click/get info/details, or use your editing software, etc.
