I have run into this issue several times over the years. My current project at [1]uses Wikidata instead of Wikipedia, as it is easy to get the "image or not" information from Wikidata, and any Wikipedia article associated with a Wikidata item could use the image there, and thus *potentially* has an image.
You can currently get Wikidata items with coordinates but no image from [2] and [3], but only [2] does "around these coordinates" queries. Also, feel free to use the API at [1], if you can figure it out. A remaining problem is that, while Wikidata has more items with images than any Wikipedia (save en, for now), there are still plenty of Wikipedia pages with images where the Wikidata item has none. One can use [4] to quickly add existing images from Wikipedia to Wikidata.
