Dezoomify V3

Dezoomify (https://dezoomify.ophir.dev/) is a terrific project by lovasoa (https://github.com/lovasoa) that lets you download full-resolution versions of zoomable images — the sort you often find on museum, library, and other archival websites. Because these images are massive, the sites often present them via smaller image tiles that are stitched together in real time. Dezoomify helps you unite all those tiles into a single downloadable image.

There's also a dezoomify Chrome extension (https://lovasoa.github.io/dezoomify-extension/) that handles a key part of the process: detecting the exact url of the zoomable image on a given webpage so it can be handed off to dezoomify to process. Unfortunately, the extension hasn't been updated in years and still uses Chrome's deprecated Manifest V2, meaning it's been removed from the Chrome Web Store and unavailable for users.

All this version of the dezoomify Chrome extension does is update it to Manifest V3 so it can be used again in Chrome and other recent Chromium browsers. The original README from lovasoa is below.

Download zoomable images from web pages

This browser extension detects zoomable images in web pages and allows you to download them. It works with the websites of many different museums, art galleries, libraries, and numerous other sources.

How to use :

- Install the extension
- open a zoomable image in your browser
- click the grey magnifying glass icon in the address bar
- the icon should become blue, denoting that the extension is now actively listening for zoomable image requests
- zoom into the image or reload the page
- if the extension detects zoomable images, you should see a small badge appear over the icon specifying the number of images found
- click the icon to open the image in the dezoomify website
- click "dezoomify", and wait while the image downloads at maximal resolution
- right-click on the downloaded image, and choose "Save As" to save it as a PNG file on your computer
