How to add an image to a gist
Create or find a gist that you own.
Clone your gist (replace
<hash>with your gist's hash):
# with ssh git clone email@example.com:<hash>.git mygist # with https git clone https://gist.github.com/<hash>.git mygist
Change to your gist’s directory:
Add and commit the image:
git add tulip.jpg git commit -m "Add tulip to gist"
git push origin master
See blog post.
It reorders the images in my case. But thanks anyway.
