Hi;
 I forgot to select category while upload my photo. Now i can't remove or edit photo. Web users can see photo on galery but when they click to image, fatal error happaned like below

Fatal error: Call to a member function on a non-object in /home/mysite/public_html/components/com_rsgallery2/templates/meta/display.class.php on line 234

How can i remove this photo ?
