Any online image that puts the Reputation of a man/company in the dock is known as negative image. As picture is like thousand words, obviously the impact of picture is also far far greater than the negative content.
If you are a popular figure, you are bound to face the heat of the people. Some people may post your negative images on Web, just to score some points. Imagine a situation: Someone is very inquisitive to see you on the Web. He/she clicks an image of you, but, that image takes the person to a picture, you might not want to watch. In short,
Any negative picture will prove to be suicidal for your aspirations.
"Reputation is an idle and most false imposition; often got without merit, and lost without deserving."- William Shakespeare
