Image field

Image field only requests the following informations:

[
	'slug'   => 'swimming_pool_photo',
	'type'   => 'image',
	'labels' => [
		'label' => 'swimming_pool_photo_label',
		'help'  => '',
	],
],

The labels key contains the keys for retrieving the labels from the labels array at the root of the entity declaration. Eg:

$declarations[] = [
	'entity'   => 'Webaxones\Core\Option\SettingGroup',
		'labels'   => [
			'swimming_pool_photo_label'    => __( 'Swimming pool photo', 'webaxones-content' ),
		],

The image field offers a clickable button on which we can also drag and drop an image that will be uploaded to the media library and displayed below the button.
