I'm falling apart?

Digital group today.  As you can see we tried a tutorial on how to make a photo mosaic portrait.  Here if you are interested!

I went straight into a problem: CS5 does not have Contact sheet II in Automate so we found a plug in but had a lot of trouble making it work - Ro was helping as he knows much more about software than me!  Finally it decided to work!    (I haven't yet worked out how to move the 'pattern' around.  some darker patches on the neck would be good!)
