Is that possible?

What I want to do is, using RMagick, create a ImageList with the gifs  
containded in a folder, so the script would first record the names,  
and then pass them to the constructor of the ImageList. It would be  
something like this (if this worked):

#arguments passed to the constructor ImageList.new  
args = []

dir = Dir.new(“gifs”)  
dir.each do |nombre|  
#populate the arguments array  
args.push(nombre)  
end

list = ImageList.new(args)

Thank’s in advance.
