Face Recognition in iPhoto

Being new to Mac, I'm used to using Picasa on my PC to catalog photos. But when I try face recognition on iPhoto, it is not only extremely slow, but the accuracy of matches is almost laughable.

Is there some reason for this, or is it just that Pisasa uses a better algorithm

Face recognition can be unreliable. I have a boulder, pond, cluster of leaves, clouds and so forth pegged as "faces". I wish I could post them here, but they seem locked in to iPhoto.

Screen shot?

I guess not because:

"The Dimension limits for this filetype are 1500 x 1500. We were unable to resize your file so you will need to do so manually and upload it again. Your file is currently 1920 x 1080."

...unless someone wants to school me how to do this.

Open your screenshot in Preview, then use the Adjust Size option in the Tools Menu.

Didn't work/couldn't figure it out so a cropped screen shot.

Yes, those are all faces!
