Beside Avatar, click Choose file to upload a profile image that customers will see in the chat window when agents respond. For best results, use an image with a 100 x 100 resolution.
While the uploaded image has a square border in the Avatar field, please note it actually has a circular border when it appears in the Agent interface and in the customer’s chat window. Finally, there is no default or placeholder avatar, which means if you don’t upload an image, the agent will have no avatar at all.
