I recently moved gallery from a Windows to a Linux system, and had to search around the forums for help. Since I didn't readily see a topic dedicated to this, I figure I'd document what I did, in hopes of helping others with a smoother transition.
- chown -R apache <albums directory>
- install netpbm, binaries (not netpbm itself) located /usr/bin
- manually modify entries in config.php:
- albumDir
- tmpDir
- movieThumbnail
- pnmDir (from above, /usr/bin)
- userDir
- chmod 777 .htaccess config.php (under gallery directory)
Your netpbm directory may vary.
