You mean, to get the URL of an *image*?
This is what I see right-clicking an image.
Your shortened list suggests that you are not clicking a raw image. I often see that when "clever" web-coding is done, as for ads. Example: The "diyaudio" logo image top-left of the forum is also a link, and the browser is reluctant to treat it as an image. I can decipher it in "Inspect Element.." but it is not easy.
