You are using Python 3 and type(str) returns "<class 'type'>"?

Binary data in Python 3 should be an instance of the 'bytes' class, not
an instance of the 'str' class.

If you can't fix that, you could turn the string into bytes using:

     data = bytes(ord(c) for c in str)

or by carefully choosing an encoding which would give the same result:

     data = str.encode('latin-1')

Then you can save it:

     s = open('/home/hidura/test.jpeg', 'wb')
     s.write(data)
     s.close()

I asked you to look at the result of repr so that you could see more
clearly what the data actually looked like, an instance of str or an
instance of bytes.
