Looks interesting. The problem with QImage is that in theory it supports all 
KIO::PreviewJob needs via QImage::text() and QImage::setText(), but in Qt 
3.0.x the PNG reader just doesn't read those chunks from the file in 
non-progressive mode. How fast is KFMI? I still tend to prefer a plain QImage 
approach though since in case the thumbnail is up to date (which is 
determined from those tags), then we have the needed QImage already. Also, it 
would fit well together with the corresponding setText() calls when creating 
the thumbnails. Oh well, guess I'll give KFMI a try.
