Image Max URL is a program that will try to find larger/original versions of images and videos, usually by replacing URL patterns.
It currently contains support for >9000 hardcoded websites (full list in sites.txt), but it also supports a number of generic engines (such as Wordpress and MediaWiki), which means it can work for many other websites as well.
It is currently released as:
- Userscript: (most browsers)
- Stable: userscript_smaller.user.js or OpenUserJS
- Development: userscript.user.js (recommended)
- It serves as the base for everything listed below. It also serves as a node module (used by the reddit bot), and can be embedded in a website.
- Browser extension: Firefox (other browsers supporting WebExtensions can sideload the extension through this git repository)
- Since addons have more privileges than userscripts, it has a bit of extra functionality over the userscript
- Source code is in manifest.json and the extension folder
- Website
- Due to browser security constraints, some URLs (requiring cross-origin requests) can't be supported by the website
- Source code is in the gh-pages branch
- Reddit bot (/u/MaxImageBot)
- Source code is in reddit-bot/comment-bot.js and reddit-bot/dourl.js

The extension is currently unavailable to other browsers' addon stores (such as Chrome and Microsoft Edge), but you can sideload this repository if you wish to use the extension version instead of the userscript.
- Repository:
- Download the repository however you wish (I'd recommend cloning it through git as it allows easier updating)
- Chromium:
- Go to chrome://extensions, make sure "Developer mode" is enabled, click "Load unpacked [extension]", and navigate to the maxurl repository
- Firefox:
- Go to about:debugging->This Firefox, select "Load temporary Add-on...", and navigate to "manifest.json" within the maxurl repository
- Note that the addon will be deleted once Firefox is closed. There's unfortunately nothing I can do about this.
- CRX (Chromium-based browsers):
- Download the CRX build from https://github.com/qsniyg/maxurl/blob/master/build/ImageMaxURL_crx3.crx
- Go to chrome://extensions, make sure "Developer mode" is enabled, then drag&drop the downloaded CRX file onto the page.
- XPI (Firefox-based browsers):
- Download the XPI build from https://github.com/qsniyg/maxurl/blob/master/build/ImageMaxURL_signed.xpi
- Go to about:addons, click on the gear icon, then select "Install Add-on from From File...", and navigate to the downloaded XPI file.

As mentioned above, userscript.user.js also functions as a node module.
var maximage = require('./userscript.user.js');
maximage(smallimage, {
// If set to false, it will return only the URL if there aren't any special properties
// Recommended to keep true.
//
// The only reason this option exists is as a small hack for a helper userscript used to find new rules,
// to check if IMU already supports a rule.
fill_object: true,
// Maximum amount of times it should be run.
// Recommended to be at least 5.
iterations: 200,
// Whether or not to store to, and use an internal cache for URLs.

urlcache_time: 60*60,

//exclude_problems: [],
// Whether or not to exclude videos
exclude_videos: false,
// This will include a "history" of objects found through iterations.

include_pastobjs: true,
// This will try to find the original page for an image, even if it requires extra requests.
force_page: false,

});The result is a list of objects that contain properties that may be useful in using the returned image(s):

head_wrong_contenttype: false,
// Whether or not the server might return the wrong Content-Length header in the HEAD request
head_wrong_contentlength: false,
// This is used in the return value of the exported function.
// If you're using a callback (as shown in the code example above),
// this value will always be false
waiting: false,
// Whether or not the returned URL is expected to redirect to another URL
redirects: false,
// Whether or not the URL is temporary/only works on the current IP (such as a generated download link)
is_private: false,
// Whether or not the URL is expected to be the original image stored on the website's servers.
is_original: false,

norecurse: false,
// Whether or not this URL should be used.
// If true, treat this like a 404
// If "mask", this image is an overlayed mask
bad: false,
// Same as above, but contains a list of objects, e.g.:
// [{
// headers: {"Content-Length": "1000"},
// status: 301
// }]
// If one of the objects matches the response, it's a bad image.
// You can use maximage.check_bad_if(bad_if, resp) to check.
// (resp is expected to be an XHR-like object)
bad_if: [],
// Whether or not this URL is a "fake" URL that was used internally (i.e. if true, don't use this)
fake: false,
// Headers required to view the returned URL
// If a header is null, don't include that header.
headers: {},
// Additional properties that could be useful
extra: {
// The original page where this image was hosted
page: null,
// The title/caption attached to the image
caption: null
},

filename: "",
