I like Cyanide & Happiness comics. I have a folder, which contains 50-60 sub-folders. Each sub-folder have multiple comics in image formats.
It becomes cumbersome to switch between folders. And then again open image viewer to view the comic.
I have decided to view comics in browser itself. So, I have used node to server folders in the images directory.
User can browse comics using Left-Right arrow keys. Pressing the enter will take you back to root location. And when you are already at root. Pressing or click can take you to the desired location's first position(image)
