Wie man die TYPO3 Extension lz_gallery für REALURL einstellt, habe ich euch hier beschrieben:

// lz_gallery ext
'fixedPostVarSets' => array(),
'postVarSets' => array(
'_DEFAULT' => array (
'album-page' => array(
array(
'GETvar' => 'tx_lzgallery_pi1[pointer]',
),
),
'subalbum' => array (
array (
'GETvar' => 'tx_lzgallery_pi1[subg]',
'lookUpTable' => array (
'table' => 'tx_lzgallery_galleries',
'id_field' => 'uid',
'alias_field' => 'title',
'addWhereClause' => ' AND NOT deleted',
'useUniqueCache' => '1',
'useUniqueCache_conf' => array (
'strtolower' => '1',
'spaceCharacter' => '-',
),
),
),
),
'album' => array (
array (
'GETvar' => 'tx_lzgallery_pi1[showUid]',
'lookUpTable' => array (
'table' => 'tx_lzgallery_galleries',
'id_field' => 'uid',
'alias_field' => 'title',
'addWhereClause' => ' AND NOT deleted',
'useUniqueCache' => '1',
'useUniqueCache_conf' => array (
'strtolower' => '1',
'spaceCharacter' => '-',
),
),
),
),
'previous-album' => array(
array(
'GETvar' => 'tx_lzgallery_pi1[old]',
),
),
'view-mode' => array(
array(
'GETvar' => 'tx_lzgallery_pi1[colrows]',
),
),
'photo' => array(
array(
'GETvar' => 'tx_lzgallery_pi1[pic]',
),
),
),
),

);

Hier hatte ich beschrieben wie man die lz_gallery konfiguriert und einstellt
