You can work with the Contextual Menu and the Finder-selection using a found image.
See this by way of example:
Drag Finder selection to "Found Image" in Chrome Browser window - #11 by ccstone
From there you can right-click with Keyboard Maestro and drive the Contextual-Menu with one or more Insert Text by Typing actions.
I'm still using Mojave, so I can't check this – on Mojave there is no Finder toolbar button for Quick-Actions.
Is this still the case?
If there IS a dedicated button – you could drive that instead.
