Hey @keith.t.elliott, all the images I’ve ever used for docs have been just like that link you posted. I’m not sure if it’d be better one way or another but I do know that if you paste an image into a github box, you get a link back! So feel free to do it that way, and then just reference it in markdown like:
We just use GitHub as a free-for-life CDN service! Paste your image into any random comment box on GitHub and copy out the URL they give you. I asked Tom once if he thought they might purge old images some day, but he said that’ll never happen! WE SHALL SEE
