Well, I'm gonna sound like a horrible shrew, but you say you found the photo on Flickr, so to whom does it belong? Even if they allow for others to blog the photos, you should include a link back to them, as well as their name.
Sorry, sore subject for me, as my photos were always used without permission from Flickr, and so I left.
I was tempted to not even comment since I'm the first. Because I don't know. Here's hoping you'll tell when someone gets it right!
