Currently, ConTeXt only recognizes the type of figure from the file extension. If a filename does not have an extension, \externalfigure fails.
For example:
$ cp `luatools hacker.jpg` something
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 {\dodoubleargument\rssfeed_externalfigure}
\def\rssfeed_externalfigure[#1][#2]% {\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] This can be interesting http://www.garykessler.net/library/file_sigs.html
