Before you begin
  You must save your letterhead image in the 
Images folder in the same path where the style sheets are stored, and save it as 
letterhead_logo_<practiceid>.jpg. For example, if the practice id is 0001, then the letterhead image name should be 
letterhead_logo_0001.jpg.
 
 
 
  You can enable your letterhead image for APSO View and APSO document. 
  
Note: The resolution of the letterhead image must not be more than 700x300 pixels.
