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

Got it, finally:
\externalfigure[\directlua0{tex.write(math.random(20))}][width=
\paperwidth]
Sorry for the noise...
