The share image first uses the server configuration's logoSquareURL if it's non-empty, and defaults to the CoCalc logo if that URL has not been configured on the server. It ought to be noted that the quality of the share post image will vary depending on the image quality and size of the image hosted at logoSquareURL; that image must be at least 200px tall and ideally conforms to a 16:9 image ratio (the new CoCalc .png image added in this PR conforms to this spec).
