[Feature request] Copy an image's address to the clipboard using link hints

[Dark-Magician]

Suggestion: Copy an image's address to the clipboard using link hints.

It should function and look similar to when "Copy an image to the clipboard" is invoked, except an image's address should be copied, not the image itself.

Give it the description and command:

Copy image address to the clipboard
LinkHints.activateCopyImageAddress

This description and command follow from the existing "Copy image to the clipboard" and "LinkHints.activateCopyImage" description and command, and "Copy image address" is the wording used in Google Chrome's right-click menu.
