Download unnamed web image?

My python program signs onto the student facebook at my school and,
given email addresses, returns the associated full name.  If I were to
do this through a regular browser, there is also a picture of the
individual, and I am trying to get my program to download the picture
as well. The problem: the html code of the page does not point to a
particular file, but rather refers to (what seems like) a query.

So, if one went to the facebook and searched for me using my school
net id (msb83), the image of my profile on the results page is:

<img width="100" height="130" border="0" class="border" alt="msb83"

Using BeautifulSoup, mechanize, and urllib, I've constructed the
br.select_form(nr = 1)

br.form['fulltextsearch'] = 'msb83' # this searches the facebook for
results = br.response().read()
soup = BeautifulSoup(results)
foo2 = soup.find('td', attrs={'width':'95'})
foo3 = foo2.find('a')
foo4 = foo3.find('img', attrs={'src':'deliverImage.cfm?netid=msb83'})
# this just drills down to the <img> line and   until this point the
program does not return an error

save_as = os.path.join('./', msb83 + '.jpg')
urllib.urlretrieve(foo4, save_as)

I get the following error msg after running this code:

AttributeError: 'NoneType' object has no attribute 'strip'

I can download the picture through my browser by right-clicking,
selecting save as, and then the image gets saved as

Are there any suggestions as to how I might be able to download the
image using python?

Please let me know if more information is needed -- happy to supply
