Currently, ConTeXt only recognizes the type of figure from the file
extension. If a filename does not have an extension, \externalfigure

For example:

ah .. i see, no extension .. too tricky to support that as they we'd
need to run an identify on the image which is probably not what we want


However adding method=jpeg works, even if the image is not a jpeg!


i've made a simple 'identify' but am yet unsure how to use that in the
current lookup strategy (as i want to avoid too much overhead ...
using images without suffix is bad anyway)


I am using a script to typeset rss feed to a pdf for reading on kindle.
Some blog engines (e.g. typepad) do not set an extension for the image.
As such, I cannot control the input. For the moment, I am using a
workaround:

\let\normalexternalfigure\externalfigure
\unexpanded\def\externalfigure

{\normalexternalfigure[#1][\c!scale=2000, \c!method=JPEG, #2]}}

Notice the method=JPEG.

But, I think that I'll need to wrap a custom wrapper anyways, and some
pages contain gif images which cause luatex to crash.


I'll add a virtual type 'auto':

\externalfigure[yourname.auto]
