    eae pessoal. Estou com um probleminha e gostaria de saber se existe essa possibilidade.

    "Criei" um plugin com metabox com flexslider, e estou precisando pegar o alt ou titiulo da imagem para imprimir em um caption na image, observe o modo como eu chamo as imagens do campo:

    <div class="flex-container-eventos">
                <div class="flexslider">
                    <ul class="slides">
                    	<?php
							global $wpdb;
							$images = get_post_meta( get_the_ID(), 'capa_evento', false );
							$images = implode( ',' , $images );
									   
							// Re-arrange images with 'menu_order'
							$images = $wpdb->get_col( "
								SELECT ID FROM {$wpdb->posts}
								WHERE post_type = 'attachment'
								AND ID in ({$images})
								ORDER BY menu_order ASC
							" );
							foreach ( $images as $att )
							{
								// Get image's source based on size, can be 'thumbnail', 'medium', 'large', 'full' or registed post thumbnails sizes
								$src = wp_get_attachment_image_src($att, 'large');
								$src = $src[0];
								// Show image
								echo "<li><img src='{$src}' /></li>";
							}
						?>
                    </ul>
                </div>

    what's up guys. I have a little problem and I wonder if there is such possibility.

    "I created" a plugin with metabox with flexslider, and I need to catch the alt or image titiulo to print in a caption on the image, note how I call the images of the field:

    <div class="flex-container-eventos">
                <div class="flexslider">
                    <ul class="slides">
                    	<?php
							global $wpdb;
							$images = get_post_meta( get_the_ID(), 'capa_evento', false );
							$images = implode( ',' , $images );
									   
							// Re-arrange images with 'menu_order'
							$images = $wpdb->get_col( "
								SELECT ID FROM {$wpdb->posts}
								WHERE post_type = 'attachment'
								AND ID in ({$images})
								ORDER BY menu_order ASC
							" );
							foreach ( $images as $att )
							{
								// Get image's source based on size, can be 'thumbnail', 'medium', 'large', 'full' or registed post thumbnails sizes
								$src = wp_get_attachment_image_src($att, 'large');
								$src = $src[0];
								// Show image
								echo "<li><img src='{$src}' /></li>";
							}
						?>
                    </ul>
                </div>

    Hi, you can simply use the helper function rwmb_meta to retrieve alt text of the image, like this:

    $images = rwmb_meta( 'capa_evento', 'type=image&size=large' );
foreach ( $images as $image )
{
    echo "<li><img src='{$image['url']}' alt='{$image['alt']}' /></li>";
}

    Your code is outdated, it was in old code of Meta Box.

    For more information about the helper function, please read the documentation here.
