Are you sure this is your actual code?

py> import urllib
py> data =  
urllib.urlopen("http://13gems.com/stxresort/cart/getpic1.py?id=1&x=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.
