// Any single-image submission will redirect to the full-size image. On multi-image submissions, every page except the first will redirect to its full-size image.
// If you go "back" to the normal gallery page (to favorite the image, read its description, leave a comment, etc.) then this script will not send you forward again.
// https://greasyfork.org/scripts/4713-eza-s-image-glutton
// http://userscripts-mirror.org/scripts/show/169968 (waaay out of date)
// TO DO:
// consider doing away with 'og:' stuff for scrape_tumblr, now that redirects don't fluff up the number of pages you go Back through. consistency and simplicity have their value.
// for modify_tumblr: for photoset pages (but everywhere, to be safe) make unlinked images link to themselves. I want nice, clean, chronological tabs for multi-image comics.
// ugh. test without adblock enabled.
// modify_furaffinity to change prev/next/fav links with pre-appended #dnr. not raw html fiddling: use the DOM and getElementsByType or whatever. thingy.href=url_plus_dnr.
// flickr? maybe separately. that whole site is a mess. also full-size images are sometimes gigantic, like dozens of megabytes.
// inkbunny: move page links above first-page preview on multi-image submissions? - by altering divs or css, if possible. minimal molestation implies better future-proofing.
// weasyl: replace bespoke thumbnails with smallest preview images? eh, do these as separate scripts, once userscripts stops fucking around.
// Consider changing some @includes to @match.
// What the hell is @grant?
// Consider refactoring all Eza's scripts to create and destroy fewer variables. Garbage collection might be why these scripts are rough on CPU use.
// Is there some way to tell JS to ditch all variables? There are points in all my scripts where they're 100% finished and can mark all memory as disposable.
// Maybe change text-scrape functions to grab a large but fixed-size block of text. Or ditch html_dump entirely and use soft-scrape functions that treat document.etc as a const of absurd size.
// There's a 'delete' operator, but it only removes properties from objects. So maybe I can do var thing = new Object; thing.stuff = longstring; ... delete thing.stuff.
// I mention this because I'm not considering grabbing Pixiv pages to ensure I have full-size images with a single redirect.
// http://thehentaiworld.com/hentai-doujinshi/theres-something-about-sakura-naruto/ ? I already do rule34; there's no pretending this is just about "art."
// Almost deserves a more Pixiv Fixiv-like fix. Maybe just a link dump like that DeviantArt gallery script?
// Swagster.com? Eh. The name alone rubs me the wrong way. Ugh, and they watermark.
// Nijie.info support might be missing out on multipage submissions?
// Metabooru is either blocking the US or went down completely three months ago. Leave it in for now, just in case.
// add youhate.us to image glutton - it's literally gelbooru again -
// might've backed the wrong horse with greasyfork. openuserjs seems much livelier. mirror to there, at least. I don't want to switch over after having declared that 'image glutton has a new home.' (incidentally, "image glutton" in quotes already returns the greasyfork page.) - https://openuserjs.org/user/add/scripts -
// Since I'm just leafing through HTML (usually), can I jump to the image /before/ trying to load the page? GreaseMonkey has a wonky option for running the script before the page runs, but I don't think we get all the HTML first. Maybe... maybe AJAX the page we're on? Like, @RunAtStart or whatever, then create a little blank page, then grab the URL via XmlHTTPgetObject or whatever, then read the HTML as responseText. The trouble (I expect) would be going back to the normal page when someone hits 'back.' This script shouldn't run... but any browser will probably have cached the fake page.
// Owyn Tyler has a ridiculously replete script with similar goals called Handy Just Image - http://userscripts.org/scripts/show/166494
// The supported-site list is waaay longer than mine, and/but his goals are more complex. Image Glutton exists only to deliver the image.
// He's having trouble with back-trapping, though. His solution sounds absurdly complex even compared to mine. Test the script and recommend help if possible.
