This is addon domain's counter.py snippet tried to load an image mail.png and failed because it cant see past its document root

========================================
    # render html template and print it
    data = f.read()
    counter = '''<center>
                 <a href="mailto:support at superhost.gr"> <img src="/data/images/mail.png"> </a>
                 
                 <table border=2 cellpadding=2 bgcolor=black>
                 <td><font color=lime> Αριθμός Επισκεπτών </td>
                 <td><font color=cyan> %d </td>''' % hits[0]
========================================

While from within the same counter.py file

# open html template file
    f = open( '/home/nikos/public_html/test.txt' )

opens OK the page file which is also past addons domain's document root

Can you help counter.py to load the image? Why does it fail to load it? Python can have access to ANY filesystempath , no matter from what folder counter.py script runs from. Correct?
