Hi all,

for a presentation, I would like to have a series of images as  
backgrounds for my slides, and I want to use them in a randomized  
order. The images are named "1.jpg" through "20.jpg." So I was  
thinking of using this code:

\externalfigure[\directlua0{print(math.random(20))}][width=\paperwidth]

epecting that this should  But that doesn't work, ConTeXt doesn't find  
my pictures (I get "name: dummy" texts). Any idea what is going wrong?

Thomas
