Is placing a picture bearing the name "Muhammad" or a symbol representing him, as an expression of love for the the Prophet and a rejection of offending him, considered an innovation (bid'ah)?

"Displaying an image symbolizing defense of the Prophet, peace and blessings be upon him, is not an innovation (bid'ah). Rather, it is a defense of him and an act of sincere advice to him, as the Prophet, peace and blessings be upon him, said: 'Religion is sincere advice (nasihah).' Raising such slogans is considered a way of supporting the religion of Allah and defending the Prophet of Islam."
