Is it stealing

to appropriate someone else's blog photo? (I'm quite sure they got the picture from some other source, themselves.)
I found this picture on the jawboneradio blog.

It's part of a caption contest there. My caption would be too personal for broader acceptance, so I didn't post it there.

It would be something along the lines of,

"No, really, honey. There's a princess in movie and furry animals. All the little girls love it. Now can we watch Star Wars?"

or, "What?! A light-saber is phallic, you say? Well, I never!"
