2BC Image Gallery


The 2BC Image Gallery WordPress plugin is designed to add tags to images in the WordPress media library. Once the images are tagged and grouped into galleries, there are several options to display galleries throughout the site.

The default styling includes a lightbox to open the images in a modal window with a slideshow and back/next buttons.  The gallery screens are loaded via AJAX, with a loading icon to let you know it’s working. The display is designed to be responsive friendly, meaning it should work well with responsive themes on mobile devices. We intend to add more options around styling as we update the plugin.


The 2BC Image Gallery allows for tagging of photos (including automatic tagging of uploaded photos) with date appropriate tags. Custom tags can be added as well by editing an image and changing the Galleries section. After a few galleries have been created, it’s very simple to display them on various pages. The gallery viewer has been designed with the following features:

  • Lightbox gallery – All images open in a modal/lightbox view
  • Slideshow and Forward / Back buttons for easy browsing
  • AJAX driven – Galleries and images will appear without the page having to refresh, making for a quicker and smoother experience
  • Responsive – Ready for viewing on mobile phones or tablets in responsive themes
  • Lots of options – Use the settings page, or get technical with the shortcode or function call
  • More options to come – We already have some ideas to make this plugin even better, please visit to give suggestions or feedback, or use the WordPress support feature


The 2BC Image Gallery documentation page contains an explanation of all the settings, as well as available arguments via the shortcode and function calls. Any actions or filters that are included in the 2BC Image Gallery are also discussed here.


The 2BC Image Gallery demo page has been setup to show what the plugin will look like with different settings, as well as what is possible via the settings screen and the shortcode call.

How do I add images to galleries?

To manually apply tags to images, click Media and edit an image. The Galleries text box will appear in the right sidebar. Enter a comma separated list of galleries to add to this image. The galleries may appear in lower-case letters, but will save according to what is entered. If the image is opened in the post editor, then the familiar tag editor will appear instead of the text box.

To automatically apply calendar-based galleries to uploaded images, click Settings > 2BC Image Gallery, check Add Calendar Based Galleries, then click Save Changes.

    return $year_title;

For the month section title, include the following in your themes functions.php file:

add_filter('twobc_image_gallery_month_title', 'my_custom_month_title_function');
function my_custom_month_title_function($month_title) {
    $month_title = 'A New Custom Title For The Months Gallery Section';
    return $month_title;

For the custom section title, include the following in your themes functions.php file:

add_filter('twobc_image_gallery_custom_title', 'my_custom_gallery_title_function');
function my_custom_gallery_title_function($custom_title) {
    $custom_title = 'A New Title For The Custom Gallery Section';
    return $custom_title;
How can I change the « Back to galleries button text?

Include the following in your themes functions.php file:

add_filter('twobc_image_gallery_button_back', 'my_custom_back_gallery_function');
function my_custom_back_gallery_function($button_text) {
    // default text = « Back to galleries
    $button_text = 'New Back To Gallery Button Text';
    return $button_text;
How can I change the previous («) or next (») page buttons?

Include the following in your themes functions.php file:

Previous page button:

add_filter('twobc_image_gallery_previous_page_button', 'my_custom_previous_button_function');
function my_custom_previous_button_function($button_text) {
    // default text = «
    $button_text = 'New Previous Page Button Text';
    return $button_text;

Next page button:

add_filter('twobc_image_gallery_next_page_button', 'my_custom_next_button_function');
