I'm afraid that the more you write, the less sense you make.

that prints three bytes, "6", "6", and "0":

 >>> fileWrite = open('a.jpg','ab')
 >>> fileWrite.write('660')
 >>> fileWrite.close()

 >>> fileRead = open('a.jpg','rb')
 >>> b = fileRead.read()
 >>> fileRead.close()
 >>> print b
660

what do you want it to print ?
