<!--

<a href="#" class="envirabox" data-envira-gallery-id="1234">Load Gallery in Lightbox</a>

Perhaps Envira changed something; your code did not work for me. It would pop up the last image of the gallery, instead of the first. I had to do the following:

$('#envira-gallery-'+$(this).data('envira-gallery-id')+' > div:first-child a').envirabox().click();
