See
http://wiki.contextgarden.net/Using_Graphics#Specifying_image_directories
You need to add
\setupexternalfigures

The third \externalfigure-command (\externalfigure[test]) will work, and
the last one won't. In this example, you will get an empty third page
and the text after the \externalfigure-command doesn't appear in the
pdf. 'test' can be a pdf-file or jpeg-file (I only tested whose types of

I don't have the latest beta yet, so cannot comment on this.

Re: [NTG-context] bug in \externalfigure
You are right. I was a little bit confused, because I didn't know, that you have to add 'location=default' to get the sample files, so I thought, that might also be buggy. 'test' is a test-file (pdf, jpeg, ...) in the current directory (I have not mentioned that). In my second Mail I included the source files with 'test.pdf'. You can see the bug there or when you compile the example below. This time, the sample files are loaded correctly and you will see, that the second graphic and sentence are missing. \setupexternalfigures[location=default] \starttext \externalfigure[cow.pdf] \page This text will appear. \externalfigure[cow.pdf][width=10cm] This text will not appear. \stoptext Am 01.08.2013 um 15:52 schrieb Peter Münster pmli...@free.fr: On Thu, Aug 01 2013, Jannik Voges wrote: The first two \externalfigure-commands (with cow) will give a grey placeholder with 'state:unknown' in it.

Okay, a reader dependent bug/error. I used Preview (OS X 10.8.4). The second figure (\externalfigure[cow.pdf][width=10cm]) and the following sentence didn't appear. The same happens when you use height instead of width.

[NTG-context] Bug in \externalfigure[...][factor=max]
\externalfigure[...][factor=max] behaves incorrectly (or at lease does not
behave as expected) when the width of the figure is less than the height.
Minimal example:
\startbuffer
\startTABLE[frame=off,align={middle,lohi}]
\NC none \NC \externalfigure[cow][ratio] \NC \NR
\NC max \NC \externalfigure[cow][ratio][factor=max] \NC \NR
\NC fit \NC \externalfigure[cow][ratio][factor=fit] \NC \NR
\stopTABLE
\stopbuffer
\starttext
\subject {Width Height}
\defineexternalfigure[ratio][height=1cm,width=5cm]
\getbuffer
\subject {Height Width}
\defineexternalfigure[ratio][width=1cm,height=5cm]
\getbuffer
\stoptext
See attached output.
I thought that factor=max scales the figure (while maintaining the aspect
ratio) until the used_width asked_width and used_height asked_height.
Looking at the grph-inc.mkiv (in particular \grph_scale_apply_size), I
no longer understand what factor=max is supposed to do!
facor=fit seems to behave as expected, although I don't understand the
purpose of factor=broad (why subtract 4*bodyfont? To fit the caption?)
