I can't push the uploaded image from the app zoho creator to crm

How can i push the uploaded image to crm? I already created the code for it but its not working.

newEmployeeInfo = Map();
newEmployeeInfo.put("Name",input.Name);
newEmployeeInfo.put("License_or_ID",input.ID1);

response = zoho.crm.createRecord("Employees",newEmployeeInfo);
