I don't know if this helps but the following tells what the type of the

Thanks.
Hans implemented a version of unix file command for checking the type of
images, but using the inbuilt library is definely simpler!
\startluacode
userdata = userdata or { }
function userdata.mytype(s)
context(img.scan({filename=s}).imagetype)
end
\stopluacode
@Hans, btw I also noticed that \locfilename does not work for files
without extension. Create a file "one" in the current directory and then
run:
\message{>>>\locfilename{one}<<<}
\end
