Use googlePanicImage to display a direct 'View' link, 'image resolution/dimensions' and 'size in byte/kb or mb" on hovered images at Google Image search.
Also additional options are provided to configure and show image sizes directly on the images of the search or hide images texts.
No additional requests to any of the websites are made, the data is.. "provided" by Google. ;)
Note: The current addon/extension version should be "v5.x.x" and should be available for the below browsers.
See here: Firefox | Chrome | Opera | Edge
Version v1, v2, v3, and v4 are in place for historical reasons."gpi.js" is always the current version.
