I installed Wordpress in the MetaBox plugin and added the Image Advanced field, in the file function.php I added the following one custom thumbnails with this configuration.
add_image_size( 'destaque-pesquisa', 120, 90, true );
On the page that I want the image to appear I entered the following code.
<?php
$images = rwmb_meta('image_advanced_2','type=image&size=destaque-pesquisa'); ?>
<?php if (!empty( $images )){ ?>
<?php foreach ( $images as $image ){?>
<img src='<?php echo $image['url']; ?>' alt='<?php echo $image['alt']; ?>' >
<?php }} ?>
The image appears on the bad page without the pre-defined dimension in destaque-pesquisa
In the Meta-Box plugin's documentation it says:
$images = rwmb_meta( 'gallery', 'size=YOURSIZE' );
// Ou
$images = rwmb_meta( 'gallery', 'type=image&size=YOURSIZE' );
