Thanks for this script. Very useful.
Say is it possible to download the image only without archive, i.e one by one or only the single image if specify download one?

If you just want to download one or just a few images, you can download it manually without using the script, by clicking the link at the bottom of the viewing page or right click to save the image.

If you want to download a full gallery, it's not easy to implement it due to the browser's limitation and compatibility, you can try other tools like gallery-dl.

I just want to download original image and I have to click three buttons each time ("get original image" -> it opens in new tab -> go over there -> save as, it's a little annoying to do it if I just want to cherry pick images from a vast image gallery, I don't get it why is it "browser limitation" to make a shortcut button that fetches original image immediately?

The "browser limitation" is the script cannot access to your local storage directly, so it needs to pack all the files first (except the new File System Access API but it needs a lot of refactor and only Chromium-related browsers support it).

You can use pages range to specify the pages to download, then extract it locally. Or as I said you can try gallery-dl then use the image-range option to filter desired images.
