			plugin_dir_path(__FILE__)
		);
	}
	function modify_form($form){
		global $_wp_additional_image_sizes;
		if( !empty($_wp_additional_image_sizes) ) {
			foreach($_wp_additional_image_sizes as $i => $s) {
				$form['size']['options'][$i] = $i;
			}
		}
		return $form;
	}
	function get_style_hash($instance) {
		return substr( md5( serialize( $this->get_less_variables( $instance ) ) ), 0, 12 );
	}
	function get_template_name($instance) {
		return 'squaremedia-image-widget-template';
	}
	function get_style_name($instance) {
		return false;
	}
	function get_less_variables($instance){
		return array();
	}
}
siteorigin_widget_register('squaremedia-image-widget', __FILE__, 'SquareMedia_Image_Widget');

i know the issue can’t be on the template file because even if i just add html it doesn’t show up.
