I did change it to text/plain, but I don't know how I'm supposed to
manually
decode it. Yes, it printed out a bunch of crap to the screen. I've gotten
that far before, and once I read Adobe something, so yes, it's an image.
TIA,

Hopefully the 'crap' you're getting is the base64-encoded representation of
your binary image -- you should be able to use Python to decode that, and
then use any image viewer to verify that the JPEG is sound.
Can you remind us of the URL where that code (with the text/plain content
type) is running?

I did that. In fact, just to make things easier, I wrote out exactly
what

supposed to be rendered, as below:
#!/usr/local/bin/python

import cgi
import sys,os
sys.path.append(os.getcwd())
from login import login
user, passwd, db, host = login()

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.

Re: Problem Displaying Pics
I have come to the conclusion that this has absolutely nothing to do with
the code. The problem is eNom. I have had so many problems with this
provider specifically concerning their python interpreter that I actually
filed a complaint against them with the BBB, which they still didn't
resolve. Now that I'm back in the states and making money, I've bought space
on another server that I'm building. Let me spend my time building that, and
I believe all these silly problems will go away. I will start a new thread
if I'm wrong. Thank you all for your help!

Are you sure this is your actual code?
py import urllib
py data = urllib.urlopen(
http://13gems.com/stxresort/cart/getpic1.py?id=1x=1;).read()
py data[:30]
'Content-Encoding: base64\n\n\n/9j'
py data[-30:]
'XdjTJvaaF5fvfMVgbUM+gatZXFzb\n\n'
1) The Content-Encoding line is taken as part of the response entity (the
picture data), but should be part of the header. I bet you have a blank line
after Content-Type.
2) Note the \n\n at the end
py data = data[27:-2]
py decoded = data.decode(base64)
py open(test.jpg,wb).write(decoded)
I tried to open test.jpg, but it's corrupt.
py len(decoded)
65535
py decoded[:30]
'\xff\xd8\xff\xe0\x00\x10JFIF\x00\x01\x02\x01\x00H\x00H\x00\x00\xff\xe1
\xadExif\x00\x00'
Very suspicious file size... Looks like a jpeg image that was truncated at
that size. See whether it is already corrupt in the database and repair it
(you're using a data type large enough to hold the image, aren't you?)
After fixing the database, you can omit the unnecesary base64 encoding;
anyway I'd add a Content-Length header to avoid that spurious \n at the end.

Looking at the output, it seems the reason for this (for me) is that
Firefox can't find the image or any alt text for it, so it's just using
the image URL. Are you certain the image data (i.e. the 'content' string)

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')

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')

Looking at the output, it seems the reason for this (for me) is that
Firefox can't find the image or any alt text for it, so it's just using
the
image URL. Are you certain the image data (i.e. the 'content' string) is
correct, and being encoded correctly in the output?

If you include extra blank lines after the headers, the browser will

If this doesn't work, I suggest changing the content-type header to

Hopefully the 'crap' you're getting is the base64-encoded representation
of your binary image -- you should be able to use Python to decode that,
and then use any image viewer to verify that the JPEG is sound.
Can you remind us of the URL where that code (with the text/plain content
type) is running?

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.

That's still wrong. The output should be:

- a blank line (no more!)

- the actual image data

being printed (Content-Type: image/jpeg) should take effect.

Re: Problem Displaying Pics
I remember going round and round on this issue before until I finally got it
right. I haven't changed the code. It worked before. I just tried your
update and it gave me the same result :( Any other ideas?
TIA,
V

Re: Problem Displaying Pics
The code in question is generated automatically from another script. I took
your idea of the \r\n\r\n and added triple quoting and now it prints out
this:
#!/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()
picid = int(form['id'].value)
x = int(form['x'].value)
pics = {1:'pic1',2:'pic2',3:'pic3',4:'pic4',5:'pic5',6:'pic6'}
pic = pics[x]
print '''Content-Type: text/html
'''
db = MySQLdb.connect(host=host, user=user, passwd=passwd, db=db)
cursor= db.cursor()
sql = select + pic + from products where id=' + str(picid) + ';
cursor.execute(sql)
content = cursor.fetchall()[0][0].tostring()
cursor.close()
print '''Content-Type: image/jpeg
'''
print
print content
To answer your questions, I have no idea what eNom has done to their
servers, which is where the other site was hosted (never went live), but am
in the process of building on DreamHost, who seems to be a FAR better
service than eNom, whom I actually had to report to the BBB and they never
fixed or acknowledged very obvious problems. At any rate, the above code
gets the browser to print out all the binary garbage that should translate
into an image (you can look:
http://13gems.com/stxresort/cart/getpic1.py?id=1x=1 ). Any more ideas would
be helpful.
