How have you configured it, then? AFAICT, there are two ways
ELinks can find a program to run for a given MIME content type:
(a) Map the MIME content type to a handler name via the
mime.type.* options, and then map handler name to a program
via the mime.handler.* options.
(b) Map the MIME content type directly to a program, by reading
a mailcap file.
Which of these are you trying to use? You mentioned mime.handler.*
so I guess you're trying (a). Did you set mime.type.* too?
set mime.type.image.png = "pngpicture"
set mime.handler.pngpicture.win32 = "some-viewer %"
set mime.handler.pngpicture.win32-xwin = "some-viewer %"
set mime.handler.pngpicture.unix = "some-viewer %"
set mime.handler.pngpicture.unix-xwin = "some-viewer %"
I don't know whether SYSTEM_STR is "win32" or "unix" on Cygwin,
nor whether you have X there.

That is probably a bug in subst_file() in src/session/download.c.
It gets the name of a temporary file as a parameter. On most
systems, when it sees the '%', it calls add_shell_quoted_to_string(),
which adds 'single quotes' around the name and escapes any similar
quotes within the name. On Cygwin however, subst_file() instead
calls cygwin_conv_to_full_win32_path() and add_to_string().
I guess the result of cygwin_conv_to_full_win32_path() has
backslashes as directory separators, and subst_file() then returns
those as part of the command to be executed by the shell; but if
the shell is a Unix-like shell from Cygwin, then it treats the
backslashes as quoting characters instead.
There is this line in subst_file():
add_to_string(&name, new_path);
Perhaps if you changed it to:
add_shell_quoted_to_string(&name, new_path,
strlen(new_path));
then it would work better?
