\externalfigure won't find a metapost eps file in a subdirectory, if the
mps has the numerical (.1) extension.
Here's a minimal example (test.tex):
\setupexternalfigures[directory={fig}]
\starttext
\externalfigure[simple.1]
\stoptext
where fig/simple.1 is from a simple .mp file that fills a 1-cm box (see
below).
The resulting test.pdf shows the gray box
name : simple.1
file : simple.1
state: unknown
Only this combination of circumstances triggers the problem. Giving the
full path ("\externalfigure[fig/simple.1]") works fine, as does renaming
the file to simple.mps (within the fig/ directory), as does using
instead simple-1.pdf (made with mptopdf).
Thus, I have several workarounds, but it might be useful to figure out
what is not working. I've noticed this problem on and off for a while
now, but only now made a minimal example. (Is the path-searching code
trying to append extensions and directory prefixes at the same time, and
thus not finding the file?)
This is with MkIV 2013.05.28 from vanilla TL2013.
For completeness, here's simple.1, although any file will show the
problem equally well:

Here's the debugging info after enabling the graphics.locating tracker
(which I learned about at the very useful page
<http://wiki.contextgarden.net/Command/externalfigure>):

Hi Sanjoy,
Sorry for the late reply; I had to dig around in grph-inc.lua, and I'm
a bit rusty at source-diving.
Yep, that’s a problem all right. A bug, even: when you put `simple.1`
in the same directory as the `.tex` file, it is correctly identified
as MetaPost; when you put the exact same file in a subdirectory like
`./fig`, you get the problem you describe. No clue why.
Until Hans fixes this, you can force ConTeXt to treat a file as
MetaPost, JPEG, etc. by passing the `method=` paramater to
`\externalfigure`. For MetaPost, write `method=mps`; I don’t know why
the MetaPost code is not `mp`. (Perhaps that could be made a synonym?)
Complete example below. I hope this workaround helps? Good luck with your work!
Cheers,
Sietse

you can test with this (line 767 in grph-inc):
askedformat = format -- new per 2013-08-05
elseif trace_figures then
report_inclusion("unknown format %a",askedformat)
end

Hans, Sietse,
Thank you very much: method=mps works, as does Hans's lua code.
Best,
-Sanjoy

I suppose because `mp' is MetaPost code
and `mps' is MetaPost produced PostScript.
