I tried both of these, and they, too, gave me the same identical image of
the url, not the image I am after.

I am just really, really, stupid, Steve. Please forgive me for being so
stupid. But I am persistent. And I have built dozens of Web site with
images.

In my stupidity, I have assumed you meant this:
content = col_fields[0][14].tostring()
print '<img src="', content, '"><br /><br />'
Obviously I am wrong. Could you please give me a little more insight?

Well, I just thought it might be a good way to get the information out,
since it is not out there yet. And I believe it is only proper to give
credit where credit is due. I would not be doing this to praise you. Rather,
I would be doing this because it is needed, and I would feel wrong for not
crediting those who deserve credit. Please let me know, however, if you feel
otherwise.
TIA,
Victor
