Hi,I have created a settings page with an image_upload field (single image). I would like to show the uploaded image on the homepage. According to MB Settings Page documentation to get the field value you have to write

rwmb_meta( 'field_id', array( 'object_type'=> 'setting'), 'OPTIONS_NAME' );

This returns an array with all the image sizes and other information about the uploaded image

According to image_upload field documentation, to get just one image of the desidered size you should write

$images = rwmb_meta( 'info', array( 'size' => 'thumbnail', 'limit' => 1 ) );

I have tried to merge the two options arrays with no luck

rwmb_meta( 'field_id', array( 'object_type' => 'setting', 'size' => 'thumbnail', 'limit' => 1 ), 'options_name' );

so question is: how do I get only one image of desidered size if it has been saved in an option page?

I have be missing something trivial here but I cannot get the desidered outcome

Thank you
Michele

Hi, your code seems to correct. When specify limit it returns an array of single image. So you might want to do this:
```
$images = rwmb_meta( 'field_id', array(
    'object_type' => 'setting',
    'size'        => 'thumbnail',
    'limit'       => 1,
), 'options_name' );
$image = reset( $images );
echo $image['url'];
```
