At the moment, this is not in the native site code. However, you can load an extension for most common browsers.
For FireFox, install this extension: addons.mozilla.org/en-GB/firefox/addon/xifr/
Then if you hover the mouse over a picture and right click, an extra item is show which says 'View Exif Data'.
For Chrome (and, I assume Chrome clones such as Vivaldi, Edge and Brave), install this extension chrome.google.com/webstore/detail/exif-viewer-classic/nafpfdcmppffipmhcpkbplhkoiekndck
Then, when you hover over a picture the exif data is shown in a blue border at the top of the picture.
