Question regarding image sizes

[ackoujens]

When I read the description of this repo it says that this plugin creates an image of x2 size and x3 size. Afterwards, I'm told it "never upscales images".

How does this not affect image quality? If an image of x2 is created, AFAIK the image is created at a 200%

Thank you for making the fix. Can you point me to how I can patch or update to the patched code? I can download the zip from GitHub, but can't figure out how to install the updated GEM.
