It is not recommended to use Gallery v 03.00.12 on DNN 4.x or 5.x releases due to many issues, particularly with Friendly URLs.

Additionally, running v 03.00.12 in a live production environment is not supported and is highly discouraged. It has known issues on websites configured to work with certain locales and it has some performance and security issues that are being addressed in the next version.

In one of the last steps prior to submission of the new Gallery v 04.03.00 to the DNN release process, a short-term public beta has been made available on July 21, 2009 (for testing purposes only - not for use on live production sites).
