word limit including image

Hello
I am using this code in function.php to limit the contents to 90 words

<?php
function new_excerpt_length($length) {
	return 90;
}
add_filter('excerpt_length', 'new_excerpt_length');
?>
<?php
function new_excerpt_more($more) {
	return '...';
}
add_filter('excerpt_more', 'new_excerpt_more');
?>

it works perfectly , however, it strip the image,
is there any way that i can include the image as well ?
