The Settings -- Personal data section of the Netrox live chat software contains your personal information. The Personal card section of the left menu can be used to change the last and first name, chat nickname and photo.
First and last names are data that is needed only for internal convenience and your identification amongst other operators. This data never goes outside and the site visitors will not see it.
When you registered or were invited into the system, by default your name was placed in the Chat nickname field. In the Personal data block you can assign any other name for the chat that will be displayed to the visitors of your website.
The same rules, as to the operator name and description, apply to photo usage. The uploaded photos should belong to one of the following types: png, gif, jpg
If the window was made with custom HTML code upload, ask the administrator about the required photo size. Any dimensions can be used.
