If you're confident that the data is correct and hasn't been corrupted,  
then I'm afraid I'm out of ideas. Perhaps you could try transmitting it as  
base64, which might make it more robust in transmission and easier to  
decode and find errors locally? You'd just need to change the end of your  
script to read:

print '''Content-Type: image/jpeg
Content-Encoding: base64

'''
print
print content.encode('base64')

HTH,
Rami
