A title would be of no value to a thief or scammer unless it were signed by you, and the person also had physical possession of the car. But you can cover such possibilities by writing the word "COPY" in large letters across the picture (and, of course, not signing the title until you receive payment and have confirmed that the payment physically cleared the bank).
Ask your bank whether a copy of the title is required for a loan.
I would not accept a check; (not even a certified check) because scammers make counterfeit checks; and banks may take a week or more after a check is deposited before it is discovered to be bogus. They do the same thing with money orders. Meanwhile your car will be long gone. Cash is the only trustworthy method of payment.
