I would recommend using this plugin instead: https://wordpress.org/plugins/cpt-bootstrap-carousel/ It works well with the built-in Twitter Boostrap 3 in Roots.oi theme (Responsive) and it comes along with a CPT named carousel. Looking in your code: The get_post_gallery_images() function only returns the url and it doesn’t contain any Gallery Image Title content.
Try this: add_theme_support( ‘html5’, array( ‘gallery’, ‘caption’ ) ); And don’t forget to declare the HTML5 DOCTYPE at the very beginning of header.php with: <!DOCTYPE html>

Whenever you go through the Media Library Popup and create a gallery, WordPress … Read more
WordPress actually uses a Built-in Post Type for Attachments ( called attachment ) so you can use some of the same functions like get_the_title() which is what you’re looking for. Though, I did take some liberties by modifying your code below, using a foreach instead of a for loop: $gallery = get_post_gallery( 7, false ); … Read more

It provides several field types, one … Read more

So when I displayed them on my page, desktop size, in a row of 4, the thumbnails were getting stretched to 282 x 282px. I changed it to this new size and used a … Read more
You could use the get_post_galleries_images function, which returns an array of all the galleries from whatever post ID you specify. The following is a quick function that will display all the images: function na_get_gallery_image_urls( $post_id, $number = false ) { $post = get_post($post_id); $count = 0; // Make sure the post has a gallery in … Read more
I’m used to deal with ACF configurations and I think that the solution to your problem is quite simple, and is integrated in the ACF “gallery” field configuration options. Check out this link, where you will find described all the options for a “gallery” field. As you will see, there’s a parameter “minimum selection” which … Read more
This is the correct way to achieve it is this: function show_main_image($object, $field_name, $request){ $custom_fields = get_post_custom($object[‘id’]); $main_image = $custom_fields[‘main_image’]; $arregloimg = explode(‘,’,$main_image[0]); $image_urls = array(); foreach ( $arregloimg as $key => $value ) { $image_urls[] = wp_get_attachment_url($value,’thumbnail’); }; return $image_urls; }
