[Plugin: WP User Frontend] How to load an image from custom field

I got this code from another topic

<?php echo get_post_meta( $post->ID, ‘cf_Location’, true); ?>

I changed the cf_location to cf_thumbnail but when the code is outputted it shows this

Thumbnail : http://gravatar.com/avatar/1043d175f99fa78b4afdfc69cbcf12fb?s=80

How can i just get the link part without the “Thumbnail :”

Thanks.
