Huh, so for so depictions/thumbnails, one needs to join wikidata resources over owl:sameAs and select its dbpedia/wikidata/images. That should work, thanks.
Not sure, if it worth repairing.
@kurzum I would assume it is worth – otherwise, the dataset doesnt contain even basic information like the gender of a person, which seems pretty important (?), without also taking the above mentioned route with owl:sameAs/wikidata-resource
For example, http://dbpedia.org/page/Hans_Sarpei knows that Hans Sarpei is male, https://dbpedia.demo.openlinksw.com/page/Hans_Sarpei doesnt.
