Found the solution myself. Edit the /piwigo/themes/bootstrap_darkroom/template/thumbnails.tpl Change the line : `is_cached()}src="{$derivative->get_url()}"{else}src="{$ROOT_URL}themes/bootstrap_darkroom/img/transparent.png" data-src="{$derivative->get_url()}"{/if} alt="{$thumbnail.TN_ALT}" title="{$thumbnail.TN_TITLE}">` to `is_cached()}src="{$derivative->get_url()}"{else}src="{$ROOT_URL}themes/bootstrap_darkroom/img/transparent.png" data-src="{$derivative->get_url()}"{/if} alt="" title="">` No more popup!
