 > but I still don't understand the need for the first parameter (since
 it's always an empty string).. :?

 Think of it like this, The empty string IS the gallery content.

 If $attr was passed in as the first param, then it would be filtering the
 $attr array, Which could give the wrong impression. $attr is mearly extra
 information, its not whats being filtered.
