Yes, this seems to be the correct behavior.

I don't know the locations where the images will be loaded. I mean it
will vary from page to page. There is a method -
QAbstractEventDispatcher::registeredTimers ( QObject * object )

Can it be used in some way? To which Object timers are attached? Frame/WebPage?
