Images are loaded dynamically and directly drawn over tainted canvas, when reading comic. Using todataUrl or toblob fails.

Before any direct url be obtained. Heres a mutation observer approach that worked for me on bilibilicomics

APPROACH 1:

var img = []
    window.onload = function() {
        const observer = new PerformanceObserver((list) => {
            list.getEntries().forEach((entry) => {
                if (entry.initiatorType === 'img') {
                    console.log('Image URL: ', entry.name);
img.push(entry.name)
                }
            });
        });
        observer.observe({ entryTypes: ['resource'] });
    };

Just before the comic pages starts loading if this mutation observer is Executed on domain then it logs every direct image urls. However it may fail to capture some urls maybe they got loaded before observer starts.

APPROACH 2: Scroll comic strip till end and all pages are loaded; Then

// Fetch all resources from the network tab
const resources = window.performance.getEntriesByType('resource');

// Filter out images from the resources
const images = resources.filter(resource => resource.initiatorType === 'img');

// Extract the URLs of images
const imageUrls = images.map(image => image.name);

// Print the URLs of images to console
console.log(imageUrls);

APPROACH 3: (FULLPROOF)

imageArray = JSON.parse(document.querySelector('script#__NUXT_DATA__').textContent).filter(item => {
  if (typeof item === "string" && item.includes("jpg")) {
return true;
  }
  return false;
}).map(function(item) { return "https://static.comicfans.io/" + item;})
