[stylist] Amazon book description question

[Ann Bliss]

    Donna and others,
     I am assuming that when you upload  a book to Create Space or 
Smashwords or Amazon directly, you, the author, can write the description 
copy as well as the info about the author?  Does Create Space offer you the 
possability of creating an author page or do you do that afterwards?  If 
someone writes a poor review of your work, is there any way to get it 
retracted or is it thee forever? How do you upload other immages to Amazon 
other than the cover?
Ann
