Multiple Images with a Loader

Question

I am trying to load and display multiples images with a Loader, one after another. The program only displays the last image to be loaded and added to the stage. What is wrong? Here is my code..
---START OF CODE---------------------------------------
import flash.events.MouseEvent; //Package needed for mouse events
btnGenerate.addEventListener(MouseEvent.MOUSE_DOWN, buttonPressed); //Button click listener
chkSeal.addEventListener(MouseEvent.MOUSE_DOWN, chkTriggered); //Check box click listener
//If the check box is toggled, switch to 8 or 9 max characters
function chkTriggered(event:MouseEvent):void
     if (chkSeal.selected == false)
          txtInput.maxChars = 8;
     else
     txtInput.maxChars = 9;
function buttonPressed(event:MouseEvent):void
     var pictureLoader:Loader = new Loader(); //Picture loading variable
     var plateText:String = txtInput.text; //Plate text string
     var filename:String; //Filename for each character's associated picture
     var currentX:int = 10; //Current x position
     var i:int; //Counter to use in for loop
     plateText = plateText.toUpperCase(); //Convert plate text to upper case
     //For every character in the sequence
     for(i = 0 ; i < txtInput.length ; i++)
          filename = "/Numbers and Letters/" + plateText.charAt(i) + ".png"; //Generate filename
          pictureLoader.load(new URLRequest(filename)); //Load the picture
          addChild(pictureLoader); //Add picture to the stage
          pictureLoader.x = currentX; //Move picture into position
          pictureLoader.y = 366; //Constant y position for all images
          currentX = currentX + 52; //Increase the current x (by the size of the images)
     txtInput.text = "Done!"; //Display done in the text box

You appear to only have one Loader instance working for you.  A Loader can only hold one load at a time.  Try creating new Loaders within the loop.
