Of course, you _need_ to use a resource file, that you compile with pyrcc4
and import accordingly. E.g.

import test_rc
[...]
	iconfile = QtGui.QIcon(':/image1.png')


The test.qrc may look like:

<RCC>
  <qresource>
    <file alias="image1.png">img/image1.png</file>
  </qresource>
</RCC>

pyrcc4 -o test_rc.py test.qrc

Having all resources included in one executable is the reason for pyinstallers 
existence..
