My thumbs aren't showing in the product info page, but are showing in the product listings. I just installed image handler. When I go to manage the images I get this error message:

Warning: strstr() [function.strstr]: Empty delimiter. in /usr/home/darkdesire/domains/adarkdesire.com/public_html/zen/includes/classes/bmz_image_handler.class.php on line 126

Could this problem be related to the above?
