// 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// http://userscripts-mirror.org/scripts/show/169968 (waaay out of date)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: modify_pixiv and possibly modify_tumblr, to make links point to images, instead of struggling with more honest redirects
// for modify_tumblr: test for existence of _1280 etc. links before changing them - they won't 404, but they'll return funky error xml
// maybe use fake html for this, it was decently usable (separate script for seperate goals!)
// 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.
// consider redirecting to something like "data:text/html,<img src='http://example.com/image.jpg'>" instead of the plain URL. custom html would allow next/previous browsing on some sites.
// "blob://" allows binaries, if you can download the image and relay it. no idea how Image Toolbar would handle naming those files.
// ugh. test without adblock enabled.
// imgur single-image pages. really, why not?
// 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.
// Some guy says Weasyl is redirecting to avatars, but I can't reproduce that - hopefully the '/' fix for grabbing full-size links fixes his issue
// when doing comparisons in the future, remember that !== and === don't coerce types (requiring manual conversions), but != and == do.
// SoFurry shouldn't redirect from stories: https://www.sofurry.com/view/719417#dnr
// 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.
// https://openuserjs.org/user/add/scripts
// http://www.pixiv.net/member_illust.php?mode=medium&illust_id=44302315#dnr is apparently a video? ah, no: it's define as data://. wtf.
// Consider changing some @includes to @match.
// What the hell is @grant?
// 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.
// 2.0 - general solution - foreach image on page, redirect to the biggest (iff the biggest is significantly larger than the second-biggest, to avoid redirecting to ads or banners on low-res submissions
// with this, I could ditch the giant for-each and just add oodles of this-looks-like-a-submission-page @includes at the top
