# Replacing a large logo icon (snippet/snippet) with a promotion banner

** _The snippet_ ** can be modified. To do this, go to **Control Panel → Settings → General**, and upload the required image in the **Large logo icon field**. The image size should be 1024x1024px. This setting is responsible for the image that is added when the link is sent. The logo of the service and companies will remain unchanged.
