This userscript unsquashes inline images in comments by fetching the source image and downscaling it to 50%.
Requires *monkey extension to run (greasemonkey, tampermonkey, violentmonkey, et al)
Edit: also updated it to support the thread index

Alright, I’ve updated it to 0.0.5 and now it handles both inline and fixed-size index thumbnails. The thumbnails on the index get cropped to fit the hard dimensions of the squares and maintain the correct aspect ratio. In the case of inline images, they just get scaled to 50% of the original size with no constraint on the height.
