SSL certificate needed?

[Robert Hartung*]

Hi all, 
  This may be too basic a question but I would like some 
opinions.  So here goes: 
   
We are setting up a small web viewer to distribute medical 
x-ray images and reports under SSL.  We will be collecting no 
information from the clients.  This is a one way street.  We 
plan on using SSL, but I wonder if it is necessary to pay 
Verisign US$1600 every two years for their certificate? 

Thanks.  All input appreciated.
