Hi Christian,
Welcome to BuddyDev.

Are you using the customizr theme from wp.org? Is it the latest? Please let me know. I will need to download and test in order to assist you.

Thank you

Hi Graham,
Thank you for posting.
Do you mean creating a new plugin for this purpose or using the existing one?

Thank you

Hi,
Please upgrade to 1.1.6 and then you can put the following code in your bp-custom.php

/**
 * Filter wall gallery title
 * 
 * @param string $title name of the wall gallery.
 * @param array  $args {
 *  Context details.
 * @type string $component component name(e.g groups|members|sitewide)
 * @type int    $component_id numeric component id( e.g group id or user id based on the component)
 * @type string $type media type(e.g photo, video,audio, doc etc)
 *
 * }
 *
 * @return string new title
 */
function mpp_custom_wall_gallery_name( $title, $args ) {

	// in this example, we are going to change the title for the groups wall gallery like this
	// <group name> wall gallery.
	if ( 'groups' === $args['component'] ) {
		$title = sprintf( '%s wall %s gallery', groups_get_group( $args['component_id']->name ), mpp_get_type_singular_name( $args['type'] ) );
	}
	return $title;
}
add_filter( 'mpp_wall_gallery_title', 'mpp_custom_wall_gallery_name', 10, 2 );

That will do it.
