Is it possible to just crawl images using this package?

[FritzAgency]

Was wondering if it is possible to crawl the web for just images using this package. If possible, please how?

Unfortunately now there is no special API for getting image urls from a given page and during crawling binary content such as images will be omitted by the crawler, instead a placeholder '<<...binary content (omitted by js-crawler)...>>' will be included into the response instead of the actual content.

In the future it might make sense to provide a special flag to crawl/report in the callbacks only binary content such as images. This will be a new feature.
