Something like digiKam? It's a desktop GUI application with custom metadata support to manage personal photo collections. https://www.digikam.org

I don't know if image database and digital asset management are the same as photo management software or something more. digiKam doesn't have auth, security, multi-tenant etc. if that's what you're looking for - it's not a backend server.

thanks for the advice. at the end I am looking for something like digikam but web based and with basic user management.
