Don't know how this pic came to be

Can someone tell me what the symbol in the bottom right corner means?

The Details show a filename ending EFFECTS. And it is possible I did it myself, I guess.

If you hold the symbol in the bottom right, it will toggle the original picture compared to the edited picture. This is an effect via some photo editing app.

Thank-you Assassin. You are correct, and also I just found the three stars in the corner in the list view, indicating Google+ has done an automated edit. Too bad it chose the only blurry original in the batch.
