// Synopsis: 1. Create page as normal.
    // 2. Add PhotoAlbum <head> elements to normal html
    // <head>.
    // 3. Create a <div> where you want the PhotoAlbum.
    // 4. Print output from $album->generate_html_content.
    // 5. Close the </div>.

    // have access to the webpage template or can't use the
    // method shown in "embedded.php".

    // read the current ob into a string, then uses the
    // preg_replace() function to replace the </head> tag with
    // the PhotoAlbum headers prepended to it. Then just print
    // the string and it will re-populate the output buffer.
