Bookwalker Cover Grabber

Book Walker's often very large volume covers can be very useful for use in making character images or banners, or simply to have a very high quality cover you can immediately upload to the website for the XL cover feature.

  • Make a new bookmark and paste the following JavaScript in the Address/URL field:

javascript:(function(a){var b=document.createElement("textarea"),c=document.getSelection();b.textContent=a,document.body.prepend(b),b.style.position='fixed'}("https://c.bookwalker.jp/coverImage_" + (parseInt($('meta[property="og:image"]').attr('content').split("/")[3].split("").reverse().join(""))-1) + ".jpg"))()

Image Max URL, a website and userscript that redirects images to the original versions, has Bookwalker functionality included as of 0.74 - https://github.com/qsniyg/maxurl.

Please be aware that the userscript affects a large number of sites, which may not be desired.
