does the qrc_*.obj file get generated? Is it about as big as all the images 
combined?

If you open the qrc_*.cpp file you should see from the generated comments 
which files were included. Do you find the images you expected?

Check the *.qrc file, are those the same file names that you are using?

E.g.:
<file>hallo.png</file> --> ":/hallo.png"
<file>hello/world.png</file> --> ":/hello/world.png"
<file alias="foo.png">bar.png</file> --> ":/foo.png" (with the content of 
bar.png)

If you try to open one of those files directly what happens. Insert something 
like this to your code:
QFile testfile(":/foo.png");
if(testfile.open(QIODevice::ReadOnly)) qDebug()<<"Can open foo.png";
else qDebug()<<"foo.png missing, probably no qrc included";
testfile.close();

If this tests successful: you are probably using an image format that does not 
get loaded when you start the application. Check your imageformat plugins.

As a last resort: use something like GammaRay to check what gets included in 
your program.

I feel generous: I forgive you. ;-P
