Get url of edited/cropped image

Hello,

Hoping that someone might be able to point me in the right direction. Are there any wordpress functions to get the url of an uploaded image that has been cropped/resized within the media gallery? wp_get_attachment_image_src only has the native size variations. At the moment I’m fudging it with the below after getting the original image ID from the post table…but it’s a but clumsy…

$croppedpic = get_post_meta($row->ID,'_wp_attached_file', true);
        if($croppedpic){
        ?>
        <img src="<?php bloginfo('template_url');?>/images/<? echo $croppedpic; ?>" />
        <?
        }

Thanks!
