Photobombing - when a pic (or video) gets an unexpected guest in the frame - is back in the news.
It's after a clip showed a BBC newsreader get upstaged by what looked like a giant spider snacking on a fly.
And at last month's Commonwealth Games, Her Majesty the Queen got in on the action, appearing in the background of two Aussie athletes' selfie.
