Image Test - Which Woman Converted More Visitors?

They've got a great test over at Which Test Won comparing the conversion rate of two different images of women in debt.

One is a sad younger woman, the other a slightly older woman in a grocery store.

I won't spoil it for you. Go over and see if you can guess which version had a 33% higher click thru. 

And be sure to read the comments to get some insight into why one image performed better than the other.
