hello everybody,

i’m just trying to know this RoR better. And I have a question:

- i have a 
 in my scaffold.css and it has a background image. I  
actually have 5 background pictures and i’d like to use one of them  
randomly. Do I have to move this div description in another .rb file  
(where i can do the random pick with ruby?) or is there any other way?

i hope it made sence.

thanks for your help,  
iM
