    Hi There,

    Love the plugin, nice and easy solution to create an image map.

    Unfortunately I am receiving the following warning messages while trying to create an image map:

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘image-mapper’ not found or invalid function name in /home/xxxxxx/domains/mastbos-parelvanbreda.nl/public_html/wp-includes/plugin.php on line 470

    Warning: Cannot modify header information – headers already sent by (output started at /home/xxxxx/domains/mastbos-parelvanbreda.nl/public_html/wp-includes/plugin.php:470) in /home/xxxx/domains/mastbos-parelvanbreda.nl/public_html/wp-admin/post.php on line 235

    Can you help me out with this?

    Thank you.

    BR,

    Richard
