i also have
ImageButtonEndcall.Attributes.Add("onmouseover", "src='images/endcallHover.png' ")
ImageButtonEndcall.Attributes.Add("onmouseout", "src='images/end-call-32.ico' ")
so onload i am adding mouseover and out code.
somehow the set interval is triggered even on hover and it behaves very randomly. how to trigger the chnage of image set interval only on click of button else it should never be called
now once i click the button the hover image remans even when i do mouseover and out
