try-catch doesn't work for loading resources. As loading a resource is an asynchronous process the error is not thrown immediately, so try-catch is not able to catch the error. In this case, error handling is done using event listeners as show below:

var myLoader:Loader = new Loader();  
myLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, loaderIOErrorHandler);  

var url:URLRequest = new URLRequest("http://....swf");
myLoader.load(url);                                  
addChild(myLoader); 

function loaderIOErrorHandler(e:Event){
    trace("Error loading image thumbnail");
}
