Some countries and officials want to make it mandatory that a photograph is labeled if it has been altered in any way by a photo editing program. do you agree or disagree with this? why do you think people believe that images should be identified if they have been altered?

First off, this isn't really a yes or no question, this is an opinion.

My opinion is that photos that have been altered in any way should be marked. These days you never know what a person will do to say, get a job, advance a political agenda, or ruin the reputation of another person. The public has the right to the truth. Therefore, altered pictures should be marked or labeled in a way that differentiates them from others.
