QT4.6.1
QtCreator 1.3.1
windows 7, windows XP

In my application I'm loading graphic using qrc file: e.g. setPixmap(QPixmap(tr(":wndicons/close_icon.gif")));
All works fine on machine where I have QT installed.

When I try to run my app on "clean" PC it fails even if I copy all possible qt dlls to my application exe folder including qgif4.dll. The program runs fine but showing only png images. What Im missing here?
