I am using GitHub Pages, Jekyll, and Prose to manage a Website. Everything works fine, besides I cannot find a way to upload images. The Prose image uploader is not working probably as discussed in various tickets (for instance here).
Since the Website is for a friend without any git or command line experience, I am looking for another option to upload images easily from the browser to GitHub. Are there any other options like this? I don't want to host the image on an external site.
GitHub just added this functionality:
