Waiting for a constructed image

Question

I am having great difficulty with an image constructed from others. Essentially, I create an empty image and fill it with a series of drawImage() commands on the graphics context. However, I simply cannot get execution to wait for the image to be finished before it's displayed.
There are a couple of places where I may need to wait- when the images are first loaded (they are stored so only one disk access is needed for each image) and when the images are scaled before drawing them to the main image.
However, despite packing my code to the gills with MediaTrackers, nothing seems to force it to wait. I've been using:
MediaTracker tracker=new MediaTracker(this);
tracker.addImage(someImage,width,height,1); //or without the scale parameters
try{
   tracker.wairForAll();
catch(Exception e) { System.err.println("Tracker error");}
//then use the image as requiredinside the JLabel that's doing the drawing, and then inside the class that loads the images. It simply doesn't work. Refreshing the output shows that the amount that gets drawn varies. Where is the delay? How can I force display to wait for the delay? It's driving me spare.
