    PHP has never been my strongest point, and I am trying something which I cant get to work.

    I am using a plugin for SoundCloud which transforms shortcode to a HTML5 player. By default the player shows an artwork, and I would like to set that function to false in the script of the plugin.

    This is the default piece of code about the artwork (from the Iframe code)

    show_artwork=true&amp

    This is the code from the plugin:

    <?php
    /*
    Plugin Name: SoundCloud Shortcode
    Plugin URI: http://www.soundcloud.com
    Description: SoundCloud Shortcode. Usage in your posts: [soundcloud]http://soundcloud.com/TRACK_PERMALINK[/soundcloud] . Works also with set or group instead of track. You can provide optional parameters height/width/params as follows [soundcloud height="166" params="auto_play=true"]http....
    Version: 2.0
