Do you have registered your kimgio to QImageIO in a way or another? Otherwise 
QImageIO will not know about it. 

(Sorry, I do not remember which function to call to register the kimgio 
plugins.)

You can test with QImageIO with code like this:

    QFile file("test,jp2");
    file.open(IO_ReadWrite);
    QImageIO imageIO(&file,NULL);

    if (imageIO.read())
       kdDebug() << "Image loaded!" << endl;
    else
	kdError() << "Has not worked!" << endl;

    buffer.close();


(And thank you for adding JPEG 2000 to KDE.)

Have a nice day/evening/night!
