One thing I have noticed... generating a website image preview no longer creates a hit to my website.
I was worried about this a couple of months back so I tested the preview - sure enough it created the same Google referral as if you clicked the link. This no longer seems to be the case.
I don't use WMT but I do have my own stats. Possibly this never showed up for WMT users but I am certain this did on my own system.
