hi

to create a page with all the geotagged images of the gallery, you can read this news: www.vincentbourganel.fr/news/carte-des-photos

Not sure what you're trying to do here but the correct URL is:
https://www.vincentbourganel.fr/news/map-of-geo-localized-pictures/

thanks fretzl for the right url :-)
of course no matter to share this tip that works with openstreetmap plugin too.
