// Create a vertical view for high-res versions of all the image links you can see.
// This includes all pages from multi-image submissions, where those exist.
// Individual images (or whole submissions) can be removed with one click.
// Each image is also a link.
// This script is no longer a mess. These notes, well, they're okay.
// Oh, and the CSS is this way because I use a tallscreen monitor. Change img.short's max-height if that annoys you.
// Scroll down past the wall of complaining to get to the code.
// It might not even be possible to identify what error code onError caught. Jesus Christ, HTML.
// Fetch still doesn't work on Pixiv.
// fetch( 'https://i.pximg.net/c/250x250_80_a2/img-master/img/2020/05/23/10/59/10/81782474_p0_square1200.jpg', { credentials: 'include' } ).then(response => response.json()).then(data => console.log(data)); - returns an empty object, but never, ever logs anything. Without credentials there's at least a CORS error.
// I literally just want to see the response. It should not be possible to not get that information - 'fine' is 200, 'fuck off' is 403, and even no response is 500.
// Oh for fuck's sake. I just tested it in mainstream Firefox to see if it was my old browser being shitty - FF still throws a CORS error.
// It's i.pximg.net from pixiv.net. Aaaugh.
// I just want to know if a fucking image file exists! This is not an attack vector - you can do <img src onerror> and find the same damn information. Domain-agnostic.
// Do old-school XMLHttpRequest()s work? I only want the head. Ugh, probably still stopped by CORS.
// Javascript: the language where reading a file is prohibited for safety, but executing it as a script is no-questions-asked.
// ... can we just run it as a script and see if it 404s? Obviously it won't work if it exists.
// At this point I just need to style=visibility:hidden when things scroll offscreen. Same size, and god willing, no VRAM use.
// Maybe an interval that does this.src=this.src for all img elements - to fight when things half-load? Can't exactly press F5.
// Array.from( document.getElementsByTagName( 'img' ) ).forEach( i => i.src = i.src ) - inconsistently effective.
// I could add ?random-number to force a reload, but that's a complete re-download, so it's inadvisable. Can I check if it failed to-- oh right, onError.
// But I need to know what the error is, since we're still removing 404'd img elements with bad file extensions.
// I should maybe move or copy the thumbnails into a top bit, like Pixiv Fixiv.
// Also, like Pixiv Fixiv, I should probably have the ability to repopulate existing sub-spans with images,
// both for "augh all PNGs slow loading" and "ah fuck loading broke."
// What I have so far could easily replace Pixiv Fixiv's current code. The spans with this.parentElement.remove() stuff, anyway; we know the image count beforehand.
// For both, I'd like to stretch a thumbnail behind an image as it's loading. I'd need non-square thumbs. Or at least I'd really prefer them.
// I guess style=backgroundWhatever:that.src? I keep adding and removing this -> that for some damn reason.
// Change the BG color to something dark. (Ego says #324.)
// Testing whether loading shenanigans work: just make images visible on mouseover.
// This accidentally ignores muted images - I'm calling that a feature.
// Ugoira animations get a spot, but don't load an image. Semi-feature. Deserves better handling and indication.
// Clunky solution to memory problems: when an image loads, remove it, and put its URL in a list.
// This script suggests a generic solution to Twitter nonsense: replace tweet divs with their media. Break classes and IDs so their infinite-scrolling JS can't remove them. No worries about their stupid random class names, since we'd just parent.parent.parent and then .replace().
// Also I could probably just .remove() the sidebar bullshit.
// Relying on onError suuucks. I categorically NEED a way to distinguish 'didn't finish loading' from 'file not found.'
// I can maybe get around this by assuming all the thumbnails load. They're tiny and quick.
// So if a thumbnail removes itself and produces a div where one file extension is expected to load,
// and that element has no children, we can infer the load failed, and start over with the three separate file extensions.
// Maybe ctrl+z instead of a per-image 're-show' button? Stick per-image-group IDs on a list, first in last out, as they're removed.
// Still might need per-submission do-over buttons for when loading is borked. Still want them, anyway.
// Be positive: have an onLoad for each image format. Signal success, not implicit failure.
// Or I guess do both: onError, check for success?
// Even just onError not removing an image if the other two are already gone would safely assume it timed out while the others 404'd.
// Getting decent. Clone Pixiv Fixiv scaling modes, via changing image class and body class. Maybe go for unicode symbols instead of words.
// E.g. <-->, the vertical version of that, the cross version... '1:1' could just be text. Point is: not English.
// I can probably also do one-page-onscreen instead of as-it-comes vertical spacing, since I have divs around each image.
// And use a damn dark mode already!
// Buttons for forward/back? Floating over top, maybe. scrollTo stuff. Ech, but it has to update as you manually scroll down, so prev/next are at least consistently relative.
// Ideally the focus is somewhere in the middle of the screen, not like, one scanline of an image counts as being 'on' that image.
// Per-image removal buttons could be larger and lower-contrast. Big easy target. Ignorable.
// Spinner widget for individual images loading? I.e., keep spinning while the page is unfinished. That might be as simple as a DOM check.
// body.onload happens repeatedly, yeah?
// Style: thinking slow rotation, lower contrast, possibly inside the other spinner.
// I probably have to set/reset body.onError every time a new big-image starts loading.
// onstalled? onwaiting? onshow, for other things. Is oninvalid different from onerror?
// Count beside spinners? 'X images, N loading.'
// I could trivially turn this into a Pixiv Fixiv replacement - right? All I need is any image URL. No JSON shenanigans.
// A stand-in for images that haven't loaded would be nice. Maybe their thumbnail, in thumbnail size. Just tell me when the top manga will affect scrolling.
// Killing the submission reeeally needs to kill the underlying images. Maybe add another sub-sub-sub-span for next_image to target, and remove that. Then reloading the submission recreates that span before calling next_image on p0.
// Come on, I can hack together previous / next page links. Only at the bottom. Doesn't trigger automatically. Just slap it in there.
// https://www.pixiv.net/en/users/1346633/artworks?p=2 -> p=1 and p=3. Needs to handle bare /artworks to infer ?p=1.
// Add buttons for scrolling to prev/next image/submission. Left-aligned, top of each image.
// Long-term issue: this looks boring on a widescreen monitor. It's all tallscreen settings. Massive negative space otherwise.
// Needs a big reload-all button at the top.
// If I'm being clunky, I can probably grab image count from the counters in the corners.
// Kinda want a "remove all first images" button. So many censored thumbnails. Japan - fuck off already. We're sorry we colonialized you. Stop ruining porn.
// Ooh, Array.find(). Pass it a test function and it'll return the first element that matches.
// This could trivially work on Baraag. (And other Mastodon sites.)
// Oh, file-extension issues in Universal Scraper don't apply here.
// e621.

// Image Toolbox on Pixiv shows the toolbox centered... with text... at the top of the screen. What is even the fuck.
// This goes beyond "CSS is bullshit." This is getting into "CSS is haunted."
// Removed the style making all spans position:relative, and that fixed the position, but there's still text. Only on Pixiv's bookmarks page. Why.
// Gelbooru is inconsistent about WebMs. Some resolve to images. Others are blank. Dunno which is better, but pick one.
// https://gelbooru.com/index.php?page=post&s=list&tags=rosiekawaii
// Gelbooru is inconsistent about images as well. https://gelbooru.com/index.php?page=post&s=view&id=5884654#dnr#&dnr

// Oh, right, JPEG. Duh. I even anticipated that.
// Still, address videos on Gelbooru. E.g. https://gelbooru.com/index.php?page=post&s=view&id=5614716&tags=rosiekawaii#dnr#&dnr
// https://img3.gelbooru.com/images/3c/23/3c2376210444f7a7da737b412c722faa.jpg
// https://img3.gelbooru.com//images/3c/23/3c2376210444f7a7da737b412c722faa.webm
// Totally doable. So how do I check for a file without just embedding videos? Ugh, might be beyond onload / onerror behavior.
// Orrrr I could check tags. Not reliable. Could be wrong. But would allow a <video> with onerror to fall back to images.
// Better idea: indicate that it's probably a video, and link to the page without #dnr&dnr. Use Eza's Image Glutton, folks.
// Obviously that's the Ugoira solution on Pixiv: "don't." So it should be how I handle Ugoiras now that they're broken-ish.
// Embedding videos is undesirable because it implies linking to them for download.
// This script is already rude on bandwidth - videos would make it a DDOS attack.
// Solution: show thumbnail, not linked. (To avoid DownThemAll grabbing the thumbnail.)
// FurAffinity?

// https://d.furaffinity.net/art/ratcha/1613453026/1613453026.ratcha_party.jpg
// Nope, needs a fetch.
// CSS-only? Absurd tangent, but GreasyFork now lists CSS userscripts. It's probably possible to replace thumbnails on gallery websites with RegEx'd full-size versions, and fallbacks for each file extension. And obviously I think you can insert a line-break ::after each image and make them full-size or max-width / max-height. But yeesh.
// Visions of replacing filter-filter-filter chains with querySelectorAll fell through because A>B[C] always grabs B... not A.
// let things = Array.from( document.querySelectorAll( 'a > img[src*="thumbs"]' ) );
// You can get all images contained by a link. You cannot get all links containing an image.
// ... though you could get the images and do .parentElement a bunch.
// .closest( 'a' ) seeeeems to work. I do not know if it prefers hierarchy or in which direction.
// https://developer.mozilla.org/en-US/docs/Web/API/Element/closest
// Oh: it is explicitly going up the chain. Kickass, perfect.
// Might use thumbnails of first image as scroll-into-view links at the top of the page.
// Maybe with Xs on each to remove things from there as well? Questionable.
// Probing is possible without thumbnails - just onLoad( classList add "ready" ). Same results, but slower. Meh.
// Genuine bugs:
// https://www.pixiv.net/user/55117629/series/87453?p=2 - gets everything but the manga. Different page format.
// Ugoira submissions display a big floating X, because those belong to the image-extension-trying block, not to each self-removing image.
// Ahh, it's because next_image would try _p0 and fail. This rewrite assumes the first image works. Maybe do cleanup in the interval?
// Dead images and possibly thumbnails take up horizontal space and cause slight movements while loading.
// Spinners don't work on Baraag.
// And how could they? We never update per-element style. Even if @animation worked, it'd be stuck there.
// Changes since last version:
// Fixed Baraag.net previous / next controls. (PEBKAC.)
