Autoriser le scrollbar

Bonjour,

J'utilise un javascript qui ouvre une pop-up à la taille d'une image définie, mais j'aimerais autoriser le scrollbar dans cet pop-up, et comme j'ai récupéré ce code, je ne le connais pas. D'ailleur le javascript je ne connais pas tellement ! C'est plus PHP moi :mouarf:

Si quelqu'un sait comme mettre le scrollbar dans ce code :
