OK. I'll presume you are right on that[1].

I was pretty much saying that the method the OP used
was inefficient, *presuming* they were going to stick
with the MediaTracker.

My reasoning was simply that it would be faster to add
all images to the MediaTracker before calling any of
the 'wait()' methods.

[1] I have no reason to doubt you, you have far more
experience with images than me.

Having said that.. Perhaps it was a bad idea to focus on the
MediaTracker at all, especially since I do not think we ever
heard the OP say that an ImageObserver implementation was not
readily available within the ..what is it you were coding?
