Access User Photo via CRM API

Access User Photo via CRM API

Hello, we are using the Zoho CRM API to get some basic information for our logged in user through https://www.zoho.com/crm/developer/docs/api/v2/get-users.html 

This works fine but we also need to get access to the user's profile picture set through the CRM dashboard.  I can tell that the url to the image when viewing through the CRM page is of the format:

{:base_url}/crm/loadProfilePhoto?usrZaid=10019457226&usrZuid={:zuid}  

where zuid is the zuid property returned from the get-user endpoint.  Is this the only way to build this url to the photo or is there a better way to retrieve it?  And if so, what is the does the field usrZaid represent?

Thanks!
