Error #2044 Unhandled IO ErrorEvent

Hello. I have am getting the error:

Error #2044: Unhandled IOErorEvent:. textError #2035: URL Not Found.

option images/1a.jpg

I can't for the life of me figure out why I am getting this error because in the same programming I have the same picture loaded in a different place and it comes up fine. And I don't know what it means by "option".

Here is the code the error is comming from:

rawImage = xd.subject[subNum].imgURL;

imageHolder = new MovieClip;

imageLoader = new Loader;

imageLoader.load(new URLRequest(rawImage));

imageHolder.addChild(imageLoader);

imageHolder.x = 128;

imageHolder.y = 165;

addChild(imageHolder);

As I said earlier, I have the same picture loading later in the programming. But I am loading it differently because in this case it loads when a button is clicked. In the code I typed above I was using it to load the picture withough any button click.

I am using XML for all of the pictures.

Do you see something wrong? Or do you have any ideas on what I could check to further investigate the situation?

Thanks for any help you have to offer!
