Play around with this at a Python prompt to see for yourself. For example:
>>> img = file('foo.jpg', 'rb').read() # use a real image filename though
>>> img[:50]
'\xff\xd8\xff\xe0\x00\x10JFIF\x00\x01\x01\x01\x00H\x00H\x00\x00\xff\xdb\x00C\x00
\x05\x03\x04\x04\x04\x03\x05\x04\x04\x04\x05\x05\x05\x06\x07\x0c\x08\x07\x07\x07
\x07\x0f\x0b\x0b\t'
>>>So, the fact that you're getting the data from a database is probably immaterial.
