If my famous relative died (intestate) leaving me the apparent heir, do I have a claim to the copyright of their image,photos? If so,how do I get it

Florida has a right of publicity statute, which you can find at http://www.leg.state.fl.us/statutes/index.cfm?App_mode=Display_Statute&URL=0500-0599/0540/0540.html. Under Florida law, you would have to be the surviving spouse or surviving child or else have written authorization from your relative to control the use of your relative's likeness.
