Not sure how to do that with it running in a docker. But i look forward to the update :)

I can't edit for some reason. If you want i can send a comic that does it. Every single one i have tried does it heh. You might consider adding a zoom feature like Cdisplayex has. Being limited to stretch to width or height isn't ideal for high resolution (or low) monitors. Cdisplayex lets you use the plus and minus keys to zoom (with lanczos) to whatever you like.

Linuxserver.io docker running on unRAID 6.2.4. Viewing with Chrome on Windows 8.1, 10 and Chrom OS.

The width is smaller that the browser (as shown) and the length is longer. I can scroll to the bottom of the image but not the top. Every single comic i have (hundreds) have the the tops cropped out in original mode. Seems silly to offer a mode that won't show the entire image of image based media heh.
