imgur-folders

This small project uses modern browsers technology to store your images. It doesn't send or gather any information about you, your browser data or imgur account, the source code is available so you can check it out.

Copy the following script:
!(function(){var a=document.createElement("script");a.src="https://danielsunami.github.io/imgur-folders/dist/main.js";document.getElementsByTagName("head")[0].appendChild(a);})() Open your browser console (chrome hit F12 or ctrl+shit+i) paste it and hit enter.
Tip: you can use up arrow key to repeat last command.

After loaded a plus tag is placed beside every image in a post and a box called "folders" should appear.

So far there is no support to sub folders. As long as the folders box appears on screen you'll only need to hit Q to place plus tags on all post's images.
