that is certainly a great idea! IIRC there was also some code to use  
the jpeg-embedded thumbnail, if available and if large enough for the  
requested dimensions.

Can you use the QFile API instead of fopen()? If not, then please use  
QFile::encodeName() instead of latin1() to preserve the filename  
encoding.
