Coppermine was designed to be a standalone app with bridging in mind (i.e. not visual integration). All visual integration efforts psoe the same problems: coppermine was not designed for this.
Existing CMS integrations are (as far as I know):
- Coppermine port for PragmaMx
- pnCPG add-on for PostNuke and Drupal
- Bridge for older Mambo version
- User-contributed bridge for Joomla!
- Deprecated e107 port (not recommended nor supported)
- Dragonfly (phpNuke clone with security enhancements and built in Coppermine spin-off)
I'm not able to recommend any of them, as I have never used them. All ports go unsupported here anyway.
