Likebox v lightboxu - potrebuji pouze doresit

Zdravím, potřebuji přidat like button ke každé fotce lightboxu zvlášť a už to skoro mám, mám pouze jeden problém...
na 13. řádku je iframe ( like button ), který ale funguje pouze s už zadanou adresou pro like, proto místo té adresy potřebuji umístit adresu daného obrázku a nevím, který atribut pro to lze použít..
