How to stop a timer in an unloaded swf?

Hi,

I have a project in which the main swf loads another into it. The swf that gets loaded has an xml driven slideshow that runs on a timer. To view what the timer was doing in the output I traced the name of each photo as the timer fired. When I unload the swf I’ve noticed that though it appears to be gone for the stage the timer continues to fire and the images are listed in the output. I know that I can stop a timer by using

 photoTimer.stop(); 

but I can’t figure out how to stop the timer in a loaded swf. I’m using this code to remove the swf

this.mc_content_box.mc_placeholder.removeChild(contentLoader);

I’m worried that the timer may be loading the photos in the background somehow and increasing the workload. Any suggestions would be greatly appreciated.

Thank you.
