You will need to install a user script manager extension to install this script.
file:///urls. So, for this script to work, you need to enable it first.
What this script does is it makes your browser as a basic image viewer. When you navigate to a local directory such as
file:///C:/Users/Condoriano/Pictures/, the script will collect list of images that are in there, then, you can use the left and right arrow keys to navigate them.
I mainly use this to read mangas offline with my firefox.
left arrow: Previous image
right arrow: Next image
G: Open go to image box
\: Parent directory
+: Zoom in by 5% of screen width
-: Zoom out by 5% of screen width
0: Toggle between original size, fit to screen and zoom size
,: Rotate image 10 degrees counter-clockwise
.: Rotate image 10 degrees clockwise
/: Reset image rotation
You can toggle every panel on/off and it will be remembered
