Could you describe your requirements a little more just to check I understand. You basically want a topic which always sends 1 message to every consumer when they start subscribing and this message changes over time right? When the message changes is it sent to all consumers active, or is it just sent to new subscribers?
You could go with durable subscribers; but then that means all messages sent to a topic are persisted until your consumer restarts. It seems like you just want 'the last one' available to new consumers? So maybe using a Subscription Recovery Policy might be cleaner... http://activemq.org/Subscription+Recovery+Policy so that you can decide what message is sent to new consumers using a cached 'last image' that is sent when new consumers start; then you just send a message to everyone when this 'last image' changes?
