 * Good day, I am using Thesis Openhook and Nextgen Gallery plugins. When I upload
   photo’s to my gallery, I get a whole list of errors with the openhook reference
   in them. It seems to happen when nextgen creates thumbnails. Here are some of
   the errors:
 * ERROR: DSC00441.JPG :
    Warning: call_user_func_array() [function.call-user-func-
   array]: First argument is expected to be a valid callback, ‘add_openhook_options_page’
   was given in /home/jtlminis/public_html/wp-includes/plugin.php on line 395

 * Let me know if OpenHook 3 has this same issue. I’ve never used NextGen before
   and will take a look if needed.
