// On manga pages, load all images without having to manually scroll to each one.
// Pixiv is terribly designed. Maybe it's a cultural Japanese thing, where they still expect single-page click-and-wait browsing like it's still 1998. The site is just openly hostile to users' time and enjoyment.
// To wit, I recommend Eza's Image Glutton, which directs from the "medium" landing pages to either the full-size single image or the manga page. Tedium is for robots.
// Ideally we'd trigger whatever mechanism tells the page to load each image.
// Three problems with that: I'm an HTML/JS amateur, the coders didn't speak much English, and - crucially - we'd still be loading medium-size images.
// So instead we're going to scrape the page for URLs, build our own no-bullshit HTML, and replace the entire Body of the page.
// Pixiv's super-paranoid anti-hotlinking mechanisms will not trigger because it only sees one of its own pages requesting these images. We don't have to worry about 403s.
// mmmaybe replace the custom click-to-advance page with a thumbnail page that instead links to the full-size images? less scrolling through meh, less looking at full-size squick, but more clicking and ctrl+w'ing.
// can I just 'touch' all the pages and force them to load within pixiv's own source? I mean, I'm essentially recreating their page now.
// I could also just regex document.body.innerHTML for big images. I think the 'small' mode scales them instead of loading some smaller file.
// <script>pixiv.context.images[1] = 'http://i2.pixiv.net/img108/img/ukaban/29548141_p1.jpg';pixiv.context.thumbnailImages[1] = 'http://i2.pixiv.net/img108/img/ukaban/mobile/29548141_128x128_p1.jpg';</script></div><div class="item-container"><script>pixiv.context.pages[1] = [2];</script><a href="/member_illust.php?mode=manga_big&illust_id=29548141&page=1" target="_blank" class="full-size-container ui-tooltip" data-tooltip="オリジナルサイズを表示"><i class="_icon sprites-full-size"></i></a><img src="http://source.pixiv.net/www/images/common/transparent.gif" class="image ui-scroll-view" data-filter="manga-image" data-src="http://i2.pixiv.net/img108/img/ukaban/29548141_p1.jpg" data-index="1">
// Should Pixiv Fixiv load real thumbnails? Pixiv provides them. It's not like Tumblr Scrape where you want to save the small images; they only exist to provide an overview.
// Using full-size images indicates when they're done loading.
// Pixiv is now screwing with Image Toolbar. The toolbar appears with big icons and text labels (doubled text labels, in fact), and middle-clicking doesn't work. I hate this website.
// Why is this script running on e.g. http://www.pixiv.net/member_illust.php?mode=medium&illust_id=47549579 ? The single @include here obviously doesn't match. Is the "?" a wildcard?
// Once the img-original thing works, add an option (using GM API) to switch between 1200-size and original-size images.
// Arg. @grant fucked me. '@grant none' says 'gm_getsetting not found.' '@grant gm_getsetting' says 'pixiv (the array) not found.' fuck your scope bullshit, greasemonkey. be unsafe and useful.
// onError should only have to suss out image extensions once per image. Break it out into a function (onError="myFunction()") and have it change the big-image src's as well as the image-link href's.
