Replace Shortcodes with HTML in Wordpress

I'm working on a WordPress site that has been using a plugin to grab amazon product images using a shortcode.

You simply insert the asin of a book into a shortcode, like this:

[amazon template=image&asin=B00FYY53B8]

When the post loads, the shortcode is converted into the actual image HTML using the URL from amazon.... so the example above would return 

http://ecx.images-amazon.com/images/I/71kIifYTccL._SL1500_.jpg

I'm using another custom plugin to build out the content for posts, and so far am just using this shortcode as part of the post content. I would like to do some other things, such as set the featured image, etc. and need that URL.

I've tried

echo do_shortcode( '[amazon template=image&asin=B00FYY53B8]' );

But it doesn't return anything. Is there a way to "execute" shortcodes in a plugin and save the output?

Ultimately, I would also like to scale this functionality so I can replace other/old shortcodes with their HTML output, and save it back to the post, essentially eliminating the use of some shortcodes in posts.

You can include this code in functions.php. And call this function in content-singular.php or the similar file in your theme.

 function updatesc_database( $post ) {
 if ( empty($post) ) global $post;
 if ( empty($post) || ! isset($post->post_content) ) return false;
 $content = $post->post_content;
 $shortc1="amazon template=image&asin";
 $shortc2="B00FYY53B8]"; //insert the number variable here
 $shortwh=$shortc1.$shortc2;
 $replace = do_shortcode($shortwh);
 $content = str_replace( $shortwh, $replace, $content );   
 return $content;
 }

                   return;
    }
    add_shortcode('form_mod' , array(&$this, 'out_put_form'));

    return 'HTML TEXT';
}
