Visits from Google in referral traffic

Hi Guys,

i am very confused about the Google analytic. its showing visits from Google in referral traffic. I don't know why its happening. Please tell me why traffic from Google coming in referral traffic instead of search engine traffic. i want to know the reason and also tell what can i do so it will show the same in search engine traffic.

:grumpy:Anybody is here who can make me understand this????????????:grumpy:

It will be google images traffic...organic = search...referal = images.
