Filter or another way to change the title of the widget in admin

Hi there. A filter doesn’t exist for changing the widget title, but you can easily create your own custom widget by extending this widget. Something like this might work (untested):

<?php
if ( class_exists( 'Simple_Image_Widget' ) ) {
	function myprefix_widgets_init() {
			// Register the widget.
			register_widget( 'My_Image_Widget' );
	}
	add_action( 'widgets_init', 'myprefix_widgets_init' );

	class My_Image_Widget extends Simple_Image_Widget {
		function __construct() {
			$widget_options = array( 'classname' => 'widget_my_image', 'description' => 'Not yours.' );
			parent::__construct( 'my-image', 'My Image Widget', $widget_options );
		}
	}
}
