title: Ask facebook to re-scrape URL
body: <p>The og:image of the website has been changed recently. The site contains more than 100 pages, each containing their individual og:image. How can i ask or force facebook to re-scrape all the pages, so that the image gets updated? Using the facebook debugger tool will be too tedious task. Until facebook re-scrape's the site, i won't be able to submit collection for the app.</p>
