RMagick and pdf:writer

hi everyone,
I wanna know if I use i = Magick::ImageList.new(“Button_A.gif”,
“Cheetah.jpg”),
can this function return a i as an image
if not I wish that u helpme to find something that I can do to collect
many pics in one pics so I can list it in pdf by pdf.image i
because when I use pdf.image.(every pics), it’s put every pics in a line
and this isn’t my goal
I want to have all the pics in one line in my pdf
