Done now. You can find a first shot on this attached.

img2pyqt.py:

    Inlines a list of images, and embed them in a Python
    module with appropriate code so it can be loaded into
    a PyQt program at runtime.  The benefit is that since
    it is Python source code it can be delivered as a .pyc
    or 'compiled' into the program using freeze, py2exe, etc.

    Each filename is stripped from ext and non alphanumeric characters,
    and 3 functions are created: fileData(), fileIcon() and fileIconSet().
    If file extension is not one of (png, xpm, bmp), the last two are
    ommited.

It leaves me to the question, how pixmaps are handled internally: 
if the same pixmap is used multiple times, do they share memory,
or does each instance occupy additional ram? Phil?

What would the nicest way to integrate this with Qt designer?
Anybody wrapped her/his mind around QMimeSourceFactory here?
