Save Mutiple Faces

Hi all, 

    I using the facedetect.c to detect faces, after detected faces, i 
will crop (cvSetImageROI) and save it to a JPEG file. But the problem 
is when there are more than one faces detected (for example, my friend 
and i standingin front of the camera) , it will return an error message 
which stated that "Sizes of Array Input Arguments Do Not Match....In 
Function cvCopy".


    I guess it is the problem at the function cvSetImageROI. So anyone 
can help on this? Thanks u very much.


Best Regards,

Oyao
