According to the function reference, get_bloginfo('wpurl') is going to be returning a URL. If you want to access the local file system, you need a real filepath, not a URL.

Try this for the first line:

$myPath = WP_CONTENT_DIR.'/uploads/'; // this is full path

WP_CONTENT_DIR is defined in the config file, and should point to the wp-content folder of your installation.
