Recommended method: follow the automatic upgrade procedure. If you're currently running Piwigo 2.2+, the Automatic Upgrade will tell you which plugin may be not compatible with Piwigo 2.5 before upgrade.
If you're running Piwigo 2.5.* you can also download the 2.5.x_to_2.5.5.zip archive that contains all new and modified files. Once you have extracted the files, transfer them onto your web server with a FTP client (like FileZilla) over your Piwigo 2.5.x installation. No database upgrade is required.
If you are running a version older than 2.5.0 and do not want to use the automatic upgrade, then follow the manual upgrade.
