You aren't the only one whose patience and endurance is being tried by 
this thread.

Take a look, for the want of anything better, at

   http://holdenweb.com/

View the source of that page, and the first image you will find inside 
it reads

     <img src="/images/homepage/hd_explore.png" alt="" height="24" 
width="142" border="0">

Then direct your browser to

     http://holdenweb.com/images/homepage/hd_explore.png

and you will see just the image. After the change I detail below, you 
will have turned your script into the dynamic equivalent of the static 
image I directed you to above.
Where you have

             content = col_fields[0][14].tostring()
             pic = "tmp" + str(i) + ".jpg"
             img = open(pic, "w")
             img.write(content)
             print '<img src="%s"><br /><br />' % pic
             img.close()

instead write

             print content

Then browse to the URL this program serves and you will see the image 
(assuming you are still sending the image/jpeg content type). Once you 
can see the image, THEN you can write a page that refers to it. Until 
you start serving the image (NOT pseudo-html with image data embedded in 
  it) nothing else will work.

Then you can start writing <img ...> tags that include your (dyanmic) 
URLs and have your script serve the images retrieved from the database.
