hi, i need help, im sorry if this is already posted but i couldnt see myself looking through 373 pages, and i did use search and found nothing

i installed image handler 2, it is working but i do get an error message on the bottom of the image_handler.php page. here it is, and it is listed 48 times for some reason.

Warning: preg_match() [function.preg-match]: Compilation failed: missing ) at offset 48 in /home/content/a/m/a/amandagero/html/admin/image_handler.php on line 54

also, the hover part for the med images does not work, is that because of this error, or do i have to do something different?
