$g2data['sidebarBlocksHtml']

Requires $gallery->setConfig('showSidebarBlocks', false); as seen above.

Basically you would only use this if you were planning on placing your sidebar in a specific location in your layout. Otherwise the sidebar is included in bodyHtml.

<?php
    if(isset($g2data['sidebarBlocksHtml'])){
        foreach ($g2data['sidebarBlocksHtml'] as $snippet) {
            echo $snippet;
        }
    }
?>
<?php echo $g2data['bodyHtml']; ?>
