@Gary : How do I reply to a http request then?

@Antoine : It not sys.stdout.buffer.write but sys.stdout.write() 
instead. But it still doesn't work, now I have empty content

#!/usr/bin/python3
import cgi, os, sys
form = cgi.FieldStorage()
all = os.listdir("/some/path/with/files/")
for x in all:
	if x.find( form['id'].value ) != -1:
		ext = x.split(".")[-1]
		print("Content-type:image/%s\n\n" % ext)
		f = open("/some/path/with/files/%s" % x, 'rb')
		sys.stdout.write( f.read() )
		f.close()
		break
