Please go to your SightMaxAgentInterface virtual directory in IIS > right click on it > Open and you will see the location of the AgentInterface folder.
Go in the Images folder and create a new folder named "operators".
The directory “operators” should contain a jpeg with the same name as the operator ID. The photo/image should have the same size as the default Operator avatar 133px × 133px.
*spaces are converted to underscore "_"
Example : If your Operator’s name is Mike Johnson, then your JPG filename should be mike_johnson.jpg
When a new chat request will be answered by Mike Johnson, then his operator avatar image will be used in the chat window.
