Can you as a fan sell fanfiction

i for a long time have been reading a lot of fanfiction. so i come across a website where a fan put a copyright infringement post on their site stating that thier fanfiction has been turned into a full on book and the photoshopped pictures added to the stories as well as the stories are for sale. so basically the way i see it this person is not only selling michael jacksons name in a story but his image also. and for self gain. is this correct. they are not ian halperin who for all intents and purposes contacted the estate for permission to write his unauthorized biography about michael jackson. i want to know is it legal because this is fanfiction and photoshopped pics to sale michael jacksons image and name for self gain.me as an avid fan of mr. jackson find this deplorable when the man's own father cannot use his son's name or image to sell products. if someone runs across this post please give me your thoughts on this. maybe i am wrong in thinking this but i feel the person should contact the estate and do it legal, or find another way to fill their pockets besides using michael jacksons name and image. a disgruntled fan.:angry:
