The URL you provided points to a JPEG image file, not an HTML article page, so there is no article text to extract as markdown from that address.
It appears to be an image hosted on the Małopolski Urząd Wojewódzki (Lesser Poland Voivodeship Office) website, likely related to local content (e.g., a photo, illustration, or graphic), but image files do not contain readable article text that can be converted into markdown.
