It sounds like you're looking to get notified in HipChat when someone visits your page? I'm not quite sure what you mean by a "promo notification" but it sounds like you'd need to integrate with the API. A good starting place would be https://www.hipchat.com/docs/apiv2. In particular, you're probably looking for the room notification method: https://www.hipchat.com/docs/apiv2/method/send_room_notification. In order to include an image in the notification, you may need to use the share file API: https://www.hipchat.com/docs/apiv2/method/share_file_with_room.
All of these options require some programming in order to implement. There are also a wide variety of pre-built integrations that you can look through at https://www.hipchat.com/integrations - perhaps there is something available that might do what you want already.
Hope that helps!
