searching for the image collection code

["Cristóvão B. B. Dalla Costa" <cbraga fs inf br>]

Hello

I'm implementing a small change to nautilus, to have a "Invert 
selection" menu option. It's done for icon view and list view, but it 
broke the image collection view and I can't seem to find its code.

Would the nautilus community be interested in my small patch?

Thanks in advance,

Cristovao
