guglielmoa,
Thanks for getting in touch! As Barry eluded to in this thread, our plugin doesn’t currently support customizing the Map Pin image. If this is something you’d like to see in a future release, I would suggest submitting it as an idea on our UserVoice page. Our team periodically reviews the most popular ideas for possible inclusion in a future release of the plugin.
Hopefully that helps to answer your question, but let me know if you need further assistance. Thanks! 🙂
