git - Gist: How are images uploaded to a gist?

Question

Here is the image file: https://gist.github.com/mbostock/5503544#file-thumbnail-png

I tried to drag-and-drop the image file in the edit mode of a gist. That didn't seem to work in Chrome and FireFox.

Update: After back and forth emails with GitHub, this feature (drag-and-drop binary files, including images) isn't supported.

Answer 1

With a little creativity you can achieve this faster than cloning. To drag/drop:

1. Create the Gist
2. Drag an image into the comment field below. This will auto-upload your image file to https://user-images.githubusercontent.com and insert markdown code in the comment field to display the image.
3. Copy this markdown code to your gist

Note: It is not required that you submit the comment.
