While I’d rather use another tools but it might be a fun exercise.
As you’ll give the pages (and not the task to find all images from a site), you could read your list of webpages, iterate over it:
- navigate to the page
- find relevant children (at first glance “” but you might have background, etc.)
- extract the url from children (handling absolute and relative path). you can keep for
- download image into related folder (with HTTP Request activity with download ressource On, for example)
