Add this in functions.php

function get_first_image_url($fetch_image) {
global $fetch_image, $posts;
$first_img = '';
ob_start();
ob_end_clean();
$output = preg_match_all('/<img.+src=['"]([^'"]+)['"].*>/i', $fetch_image, $matches);
$first_img = $matches [1] [0];

if(empty($first_img)){ //Defines a default image
$first_img = "/images/default.jpg";
}
return $first_img;
}


and use this

<span class="rss-image">
<?php echo '<img src="' . get_first_image_url($item -> get_content()) . '"/>'; ?>
</span>
