Dragon Metrics can crawl images to check for issues and provide recommendations on image optimization, such as broken image links, missing alt texts, and more.
To enable or disable image crawling for a campaign, navigate to Crawler Settings, found in the left navigation under Campaign Settings.
Change the value of Crawl Images to Yes to enable or No to disable.
Save changes before leaving the page.
Settings will take effect in the next crawl. If you don't wish to wait for the next automatically scheduled crawl, you can always start one immediately.
