One of my Flickr photo is used in the page below the sight-seeing guide sight, schmap.com.http://www.schmap.com/neworleans/restaurants_british/p=40204/i=40204_10.jpg
First I got a mail, which says “Because your photo is candidates, please submit it by link below”. I clicked the link, and linked page explains how the photo is used, and I can select submit or withdraw. If I don't want my photo being used, It's OK to withdraw.
It's OK to be used, so I submit it.
After a while, I got next mail that “your photo was chosen”.
I took the photo when I traveled USA in 1985, it's very much old. Do they understand it? I set Attribution-Noncommercial-Share Alike 2.0 Generic to all of my pictures as a default, then it probably is caught by them.
