Hurricane sandy fraud

After reading the article hurricane sandy images: dont get fooled by a fake photo. ive learned that theyre are alot of photo shop "artists". they make fake photos such as storms. which cause wide spread and not so much needed panic. The article displayed many pictures which made the article more interesting. The article was very informative on how to catch on to fake pictures created on photoshop. I also like how the article was very well written. Why do people make these pictures if they know it doesnt help anyone?
