Solved: warnings about wp_enqueue

this plugin works out of the box but has two issues. it generates several warnings and it forces you to enter a width and height even if you’re not uploading images.

Solution to the warnings:

wrap the top css/js lines in a function, then reference the function in an add_action like this.

function my_scripts(){
	$style = 'emwi-css';
	$css_file = plugins_url( '/external-media-without-import.css', __FILE__ );
	wp_register_style( $style, $css_file );
	wp_enqueue_style( $style );

	$script = 'emwi-js';
	$js_file = plugins_url( '/external-media-without-import.js', __FILE__ );
	wp_register_script( $script, $js_file, array( 'jquery' ) );
	wp_enqueue_script( $script );
}

add_action('wp_enqueue_scripts', 'my_scripts');

Solution to the image requirement:

comment out the //return $input; line around line 210.
