IH Zoom feature not working

[bluealice]

i've tried everything, and have read through the posts, but still cannot figure out why IH zoom feature is not working. In IH Admin i see the these 2 errors/warnings: >>>>>> Warning: strstr(): Empty delimiter. in /home/content/n/2/m/n2muse/html/store/includes/classes/bmz_image_handler.class.php on line 126

Warning: strstr(): Empty delimiter. in /home/content/n/2/m/n2muse/html/store/includes/classes/bmz_image_handler.class.php on line 128

Okay, I fixed the warnings and now IH 'Admin' shows the 3 sizes, BUT the zoom feature is still not working in the product listings in the center column, which is where it's really needed. Thanks...
