About this extension

Image Max URL helps you find larger or original versions of images for currently ~6200 websites (using ~3700 individual rules), but it supports a number of generic engines, which means it can work for almost any website.

Some of the websites it supports includes (full list):

Social media websites (incl. Instagram, Patreon, Pinterest, Reddit, Twitter, Tumblr, VK, VSCO, Weibo)
News websites (incl. BBC, Daily Mirror, Huffington Post, The Guardian, The Independent, Vogue)
Generic image hosting engines (incl. Cloudinary, Drupal, Imgix, MediaWiki, Wordpress)
Image hosting services (incl. 500px, Imgur, Flickr, DeviantArt, Pixiv, SmugMug)

It performs the following functions by default (everything can be modified through options):

Redirect images opened in a new tab to their larger version (if one is found)
Pressing Shift+Alt+I (or Ctrl+Shift if you installed prior to 0.8.29) when your mouse is over an image will display a pop-up with the larger/original image. This can also be triggered with a right click menu item optionally added by this extension
- The extension dynamically detects image galleries, and will let you browse through them with the pop-up (using either the provided buttons, or with the left/right arrow keys)
- The popup has a large degree of customization. If you'd rather it work a different way, chances are there's an option for that. If there isn't, please let me know :)
- Note that this currently doesn't work on Android due to a lack of trigger
Using a button on the extension's menu, it can replace all images on a page to their larger versions (e.g. to use with extensions that download all images on a page)
- This currently doesn't work on Android due to the way extensions work there

Image Max URL works by replacing URLs, and in some cases, querying website-specific APIs. For example, if you have this image:

https://pbs.twimg.com/media/DlOC3mOWsAEi1ld.jpg (1200x800)

By adding ?name=orig to the end, you will get a much larger image:

https://pbs.twimg.com/media/DlOC3mOWsAEi1ld.jpg?name=orig (4096x2730)

This does not replace using a reverse image search to find a larger image, but rather complements using one, as reverse image search engines often don't link to the largest (or original) image.

---

Image Max URL requires the "Access your data on all websites" permission as it needs to be able to find images on the page, and create the popup that contains the larger image.

This extension does not, and will never contain any kind of tracking code.
