I'm thinking of a tab on the left hand side listing faces/people, in the 
middle area an icon view showing faces for approval. This is for the process 
of face-tagging so far.

I'd suggest displaying (approved) tags in the icon view as today, for the 
picture as a whole, and the regions only in the preview. Drawing the regions 
already over the thumbnails in the icon view would be possible, but there are 
questions about performance and UI clutter.

Good point. I think yes, it fits - in fact we could not even do a real tag 
assignment at all (in the ImageTags table), but only record the assignment in 
the ImageTagProperties table.
