Whether Romans 14 applies depends on what you meant in your original post. When you said 'graven image,' were you implying idolatry?
If so, Romans 14 wouldn't really fit; Paul there is talking about food and special days, what he calls matters of opinion. Idolatry isn't a matter of opinion or disagreement; it goes to the heart of right worship, it's not a peripheral issue where Christians can agree to disagree.
