Zillow Image Downloader

/**
 * STEP 1: Make sure to *SCROLL* through all images so they appear on DOM.
 * No need to click any images.

Yeah I was getting mediaWall errors. So in summary, as of February 2025 this script worked for me after scrolling down to the bottom to load all the photos and pasting it in console. Combination of @jessereitz and @aarrtteemm's line update in one easy spot for copy paste:

const TARGET_FORMAT = "jpeg";  // Options: `jpeg` or `webp`
const TARGET_SIZE = "1536";  // Options: `1536`, `1344`, `1152`, `960`, `768`, `576`, `384`, `192`

// Load JSZip library
const script = document.createElement('script');
script.src = "https://cdnjs.cloudflare.com/ajax/libs/jszip/3.7.1/jszip.min.js";
document.head.appendChild(script);

script.onload = function() {
    // Function to download the zip file
    function downloadZip(zip) {
        zip.generateAsync({type: 'blob'}).then(function(content) {
            const link = document.createElement('a');
            link.href = URL.createObjectURL(content);
            link.download = 'images.zip';
            document.body.appendChild(link);
            link.click();
            document.body.removeChild(link);
        });
    }

    // Function to gather and zip image URLs from "media wall"
    function gatherAndZipImages() {
        // Gather the image URLs
        const mediaWall = document.querySelector('div[data-testid="hollywood-vertical-media-wall"]');
        const sources = Array.from(mediaWall.querySelectorAll(`source[type="image/${TARGET_FORMAT}"]`));

        // Try to pull the largest src URL from a source's srcset
        // srcset is in the format "<url> <size>, <url> <size>" so we split it and try to grab the last (hopefully largest) URL
        // It shouldn't really matter, though, since the regex will replace the target size with the largest possible anyway
        const imageUrls = sources.map(source => {return source.srcset.split(",").at(-1).split(" ")[1].replaceAll(/_\d+.(jpg|webp)/g, `_${TARGET_SIZE}.${TARGET_FORMAT}`)});

        const zip = new JSZip();
        const imgFolder = zip.folder("images");

        if (imageUrls.length > 0) {
            console.log('Image URLs:', imageUrls);
            const downloadPromises = imageUrls.map((url, index) => {
                return fetch(url).then(response => response.blob()).then(blob => {
                    imgFolder.file(`image_${index + 1}.${TARGET_FORMAT}`, blob);
                });
            });

            Promise.all(downloadPromises).then(() => {
                downloadZip(zip);
            });
        } else {
            console.log(`No .${TARGET_FORMAT} images found.`);
        }
    }

    // Execute the function to gather and zip images
    gatherAndZipImages();
}

Thanks!

This is not working in Firefox, Chrome, or Edge as of April '25. Getting either "Cannot read properties of null (reading 'querySelectorAll')" error or "redeclaration of const TARGET_FORMAT" depending on browser.
