Openstreatmap images are now loaded from uploads.wikimedia.org instead of commons.wikimedia.org to prevent redirects. With `image_proxy` enabled images from commons.wikimedia.org cant be loaded since they are redirected. We already discussed this issue [875] and @tiekoetter fixed this issue in PR [878]. Related-to: - [875] https://github.com/searxng/searxng/issues/875 - [878] https://github.com/searxng/searxng/pull/878 Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>
