Have you tried to put spaces between *.png?

It seems you're misleaded about using QThread. You should stop your thread using 
some thread convenience classes like mutexes or waitconditions to let thread 
know you want to finish and wait until it finishes but definitively if you call
wait and you don't do anything thread will never end!. Please send any snip if 
you want.

Hope it helps!
