As pointed out in https://www.wikidata.org/wiki/User:Underlying_lk/sandbox#commonsMedia_support_in_harvest_template , it should be relatively easy to add image support.
elif claim.getType() == 'commonsMedia':
mediasite = pywikibot.Site("commons", "commons") image = pywikibot.ImagePage(mediasite, value) claim.setTarget(image)
Instead of using ImagePage I think Link() should be used.
