User:Gapfall has reported a couple of problems when using the API to fetch information about English Wikipedia articles that have Wikidata-driven infoboxes, specifically:
Images: "the API serves up the map image instead of the infobox photo (eg. https://en.wikipedia.org/w/api.php?action=query&format=xml&prop=pageimages&titles=Sherwood%20Observatory), for articles that use this infobox"
I don't know how the API identifies coordinates/images, so I can't do much to fix this. I don't think that there is anything specific in the infobox coding that has changed except for fetching the info from Wikidata. It might be an issue with the Lua code that fetches the Wikidata info, but it's probably easier to debug on the API side to start with.
