I did that. In fact, just to make things easier, I wrote out exactly
what is
supposed to be rendered, as below:
#!/usr/local/bin/python
import cgitb; cgitb.enable()
import MySQLdb
import cgi
import sys,os
sys.path.append(os.getcwd())
from login import login
user, passwd, db, host = login()
form = cgi.FieldStorage()
db = MySQLdb.connect(host, user, passwd, db)
cursor= db.cursor()
sql = "select pic1 from products where id='1';"
cursor.execute(sql)
content = cursor.fetchall()[0][0].tostring()
cursor.close()
print '''Content-Type: image/jpeg''' # Only print one line
Content-Encoding: base64
'''
print
print content.encode('base64')
Just to reiterate what Gabriel and Carsten have pointed out, I'd suggest
changing the last few lines of the script, as the comments below indicate:
print '''Content-Type: image/jpeg''' # One header line
print '''Content-Encoding: base64''' # Another header line. Note *no*
blank line between them
print # Blank line signals the end of the headers
print content.encode(base64) # Base64-encoded content comes *after*
the blank line
If you include extra blank lines after the headers, the browser will
misunderstand where the binary image data begins, and so will see a
malformed JPEG.
If this doesn't work, I suggest changing the content-type header to
text/plain and trying to manually decode and check the image data to
ensure it's valid.
