It still the most simple and useful script for pixiv
pity that nobody is willing to maintain it or takeover.
Does everything you need to see the most of a submission. No hassle with downloading the bigger image for anything, and it's all on the mode=medium page!
Works perfectly with Context Menu Image Saver for Firefox in combination
There are few other scripts for pixiv to display full-sized images when you click a thumb, but none of those scripts can display multiple images at once when viewing "manga mode" images.
This script by phithon, does exactly that.
If a thumb links to a page where an artist stored multiple images (manga mode), this script will display them all on 1 page.
