I changed the logo of my server, in the server-data, I gave it the same name and it did not change the logo.
You need 96×96 format
Name is not relevant
Hello.
Your server logo has got to be 96x96 and you need to make sure that your server.cfg has the following in it load_server_icon IMAGE_FILE_NAME Please make sure you include the extension type at the end so it would be load_server_icon Logo.png as example
