Hi, @anon9582441. I tested the limits of NC photo galleries and sharing and found them lacking, as well. Of course, NC apps can’t be best in class for everything.
I recommend a NC installation via Yunohost which makes other apps first-class citizens alongside NC, rather than NC apps being your go-to for “all the things.”
I wrote a short article for linking your NC files to Piwigo galleries and getting a lot out of the old (but good) Piwigo ecosystem: https://opensourceit.org/blog/2020/06/18/photo-management-and-sharing/
