Pause or interrupt loading

Hi, I’ve been working on a flash project which needs to load external images for a web.

The web will need to display an image one at a time, and so if i click on a thumbnail, an image will start to load. If the user decides to click on another thumbnail to open another images, it must interrupt or pause the loading, so another loader can load the new image, so the previous image is not displayed.

The problem is, when i tried to interrupt the loader, the first loader didn’t stop loading the image, instead it loads the image together with the second preloader.

I’ve tried using loader.close(), but it does not stop the loading.
Also tried using loader.unloadAndStop(), but in my understanding is that loader wont unload its content BEFORE it completes loading.

Is there any other way to stop the loader from completing and replace it with the new loading process?

Thanks,
