File talk:Van Gogh Portrait of the Postman Joseph Roulin.jpg

I can't figure out how to replace this image with a higher resolution image version. I just see "You cannot overwrite this file." It looks like wikidata already has a higher resolution version https://www.wikidata.org/wiki/Q26220272. There is also a higher resolution verion availible from the Barnes website https://collection.barnesfoundation.org/objects/4720/The-Postman-(Joseph-Etienne-Roulin)/

The wiki directions say the wikimedia commons page is where you should be able to replace an image, but here we are. https://en.wikipedia.org/wiki/Wikipedia:Uploading_images#Reupload_existing_image — Preceding unsigned comment added by Asdf506 (talk • contribs) 04:12, 21 September 2021 (UTC)
