Answer 1

You might also try:

If you only have one size thumbnail:

$thumbnail_src = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ) );

Or...if you have multiple sizes:

$thumbnail_src = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), "size" );

Found this here:

Answer 2

This does the trick:

<?php wp_get_attachment_image_src('subgall-thumb'); ?>

Make sure you use the correct name for the thumbnail that you are calling.

Answer 3

Ok got it using simplexml_load_string

$dom = simplexml_load_string(get_the_post_thumbnail());
$src = $dom->attributes()->src;
    echo $src;

Another method are welcome.
