2. Refresh the image every 100 ml secs
3. Its the same image.... another app that we wrote writes
over the original
thanks in advance
This doesn't work at all

OK - my guess is that it was to randomize the url to prevent
caching. As much as I don't like the workaround, try something like
this: take away your sURL and make it correctly load the image
once.
Once this is working, try to set the url like this:
var url:String = "
http://localhost/frame.png?dummy="
+ (new Date()).time;
trace(url); // Just so you can make sure it changes every
time
What this is doing is changing your url every time it's
requested so it's never found in the cache. Perhaps the cleaner way
of doing this is correcting your server so the headers set
immediate expiration.
