New localConnection quest?

greetings!!

i’m linking my thumbs through the main page with specific pictures with localConnection !

i need someone who understands it well to tell me how can i make loop out of 12 localConnections(gb1connection, gb2connection…) and have a preloader for each image?

i have existing movieClip on the stage (_root.pictMC)

the code for localConnection:

 
gb1connection = new LocalConnection();
gb1connection.onReceive = function() {
loadMovie('pictures/BE01.jpg', _root.pictMC);  
};
gb1connection.connect("incomingMessage_gb1");

thank you in advanced !!!
