I just tried it on my mobile and it wasn't that bad. I thought you were giving instructions for mobile posting. Why would you need to do that on your PC? I right click on chart, click "properties" at bottom, copy url, paste in post, highlight and click "Image" on left. Jesus after writing all that, maybe your way would be faster.
On my MAC, I right click and click, "copy Image" (It automatically loads the URL so I can paste it right away in the post).
