Dp works in an office. He has a computer on his desk ( exclusively for his use) and in his office. He got a telling off from his regional manager for having a picture of us a family on the beach as his screensaver. He apparently said it wasn't appropriate as people may get the 'wrong idea' about him as the children are wearing swimsuits. 
They're his children and we're in it too, it's not some random picture of a child in a swim suit from the Internet. 
AIBU to think this is a world gone mad? He checked their policies and there is no mention of appropriate screen savers.
His screen isn't even in view when he has meetings so it's not even as if anyone would see it to get the wrong idea in the first place.
