Assuming that the ‘Code Snippets’ plugin has already been installed, here’s a demonstration of adding a lightbox_context.js?ver=3.17
<?php
// closeout php to output JavaScript directly
?>
<script type="text/javascript">
function nextgen_lightbox_filter_selector($, selector)
{
if (nextgen_lightbox_settings && nextgen_lightbox_settings.context) {
var context = nextgen_lightbox_settings.context;
if (context == 'all_images') {
selector = selector.add($('a > img').parent());
}
else if (context == 'all_images_direct') {
selector = selector.add($('a[href] > img').parent()
.filter(function() {
var href = $(this).attr('href').toLowerCase();
var ext = href.substring(href.length - 3);
var ext2 = href.substring(href.length - 4);
return (ext == 'jpg' || ext == 'gif' || ext == 'png' || ext2 == 'tiff' || ext2 == 'jpeg' || ext2 == 'webp');
}));
}
else if (context == 'nextgen_and_wp_images') {
selector = selector.add($('a > img[class*="wp-image-"]').parent());
}
selector = selector.not('.gallery_link');
selector = selector.not('.use_imagebrowser_effect');
}
return selector;
};
</script>
