Woocommerce: Creating a download link to product i

Question

Please have a look at my sample product page: http://snshpl.com.sg/product/swa-8003-t/

I'm currently using hooks to hardcode the download button (together with a disclaimer text) to appear right after all my products' meta, this is the code added in my theme's functions.php:

add_action('woocommerce_product_meta_end','disclaimer');

function disclaimer(){
    echo '<br /><br /><a href="#" class="single_add_to_cart_button button     
    alt">Download</a><p id="disclaimer-text"><br /><br />*Color Disclaimer: 
    Due to the limitations of desktop scanners and the relative 
    inconsistencies of various display monitors, the colors you see on your 
    screen may not be a totally accurate reproduction of the actual product. 
    We strive to make our colors as accurate as possible, but screen images

    page.</p>';
}

My question is how do I extract the url of the image shown and add it to the link of the download button? I've tried various methods but not sure how to access the link which I know is extracted in the file product-image.php.

Thanks in advance!

If you're on the single product page, you can add the featured image url to your custom button with wp_get_attachment_url( get_post_thumbnail_id() );

In your example:

add_action('woocommerce_product_meta_end','disclaimer');

function disclaimer(){
    echo '<br /><br /><a href="'.wp_get_attachment_url( get_post_thumbnail_id() ).'" class="single_add_to_cart_button button     
    alt">Download</a><p id="disclaimer-text"><br /><br />*Color Disclaimer:
