Adding to a DataObject

Add a has_one or many_many relationship to "Imgix::class" in the same way you would with "Image::class". See example below

<?php
use PlatoCreative\Imgix\Imgix;

class MyCustomPage extends Page
{
	private static $has_one = array(
		'Image' => Imgix::class
	);

    private static $many_many = array(
		'Images' => Imgix::class,
	);

	public function getCMSFields()
	{
		$fields = parent::getCMSFields();
		$fields->addFieldsToTab(
			'Root.Main',
			array(
				UploadField::create(
					'Image',
					'Image'
				),
				UploadField::create(
					'Images',
					'Images'
				)
			)
		);
		return $fields;
	}
}
