Animation works but wont respond to mouse events

My animation works in AS3 but wont respond to mouse events I suspect I have bitmaps and have to convert the bitmap to a sprite.

I cant do this as yet.



} 		 		private function imageLoaded(event:Event):void 		{ 			  			var Singleimage:Bitmap = new Bitmap(event.target.content.bitmapData);   				//var  bmd=Singleimage.bitmapData; 				//img1=new Bitmap(bmd); 					 		   		MyImages.push(Singleimage); 		 		//img1.bitmapData = bmd; 		 		//addChild(MyImages[0]); 		addChild(MyImages[0]); 		 		//img1.x =xx; 		//img1.y=100; 		 		//xx+=40;   		   		   		 dispatchEvent(new Event("image_loaded"));  		} 		 		public function moveChar() 			{ 				 var xpos:int; 				//removeChild(MyImages[0]); 				timej+=1; 				if (timej>=10) 				{ 					xpos=MyImages*.x; 					removeChild(MyImages*); 						i+=1; 						 						 						if (i==4) 						{ 							 							i=0 						} 											 				addChild(MyImages*); 				MyImages*.x=xpos; 				} 				 			 			MyImages*.y=100 				 			MyImages*.x+=5 			if (MyImages*.x>400) 				{ 				MyImages*.x=10; 				} 	 		 		}    		public function moveleft() 		{ 			 			MyImages*.x-=5 			 			 		} 		 		public function moveright() 		{ 			MyImages*.x+=5 			 			 		}
