Yes you have to have "&" in front of $photo. This makes $photo a reference to the element in $photos instead of a copy. If you don't have it then you will be modifying a copy of the array element and not the element itself.
See http://www.php.net/manual/en/language.references.php for a discussion of references in PHP.
