This doesn't work:

 > os.spawn(PROGLINE)

Windows doesn't understand single quotes.  You have to use double
quotes on Windows.  os.type is your friend.  It returns "unix" on Unix
and "windows" on Windows.  You have to treat Unix and Windows command
lines differently here.

Another issue:
wget isn't in PATH on Windows.  You have to provide the path to wget
yourself. 

local function wget ()
  local WGET 
  if os.type == 'windows' then
    local texmf_root = kpse.var_value('TEXMFROOT')
    WGET = texmf_root .. '/tlpkg/installer/wget/wget.exe'
  else
    WGET='wget'
  end  
  return WGET
end

In order to suppress stdout, simply read the output of wget from a
pipe.  Just use io.popen() instead of os.spawn().

Maybe a problem with special characters.  I recommend to transform all
special chars in IMGURL to hex i.e., replace "&" with "%26".
Otherwise it would be more difficult to support different operating
systems.

And if you are running your script in an arbitry directory for
testing, (no symlinks or wrappers involved), add the line

  kpse.set_program_name('texlua')

to your script and things like

   require ("alt_getopt") 

will work.

How do you handle character encodings?
