Hi there. I've succesfully added an image upload field to the CMS. However, in the CMS it's displayed as the last field under the big "Content" field. I want it to be above the standard "Content" field and under the standard "Navigation Label" field. How can I re-arrange the CMS for this page type?

Custom CMS field code used:

class Page extends SiteTree {

	private static $db = array(
	);

	private static $has_one = array(
		'Header' => 'Image'
	);

	public function getCMSFields() {
         $fields = parent::getCMSFields();

         $fields->addFieldToTab('Root.Main', UploadField::create('Header'));
         
         return $fields;
    }

}

By using the third parameter of addFieldToTab($tabName, $field, $insertBefore = null).

So, "$fields->addFieldToTab('Root.Main', UploadField::create('Header'), 'Content');" should do the trick.

Thank you Devlin, that was easier than expected.
