回複：請教: 可以把瑪麗蓮.夢露的形象放在Business website上麵嗎?

most likely, no. in general, copyright is author's life plus 70 years. whatever the portrait you intent to use, most likely, Marilyn Monroe's estate or the photographer or maybe a corporation own(s) the copyright (or jointly). Don't confuse copyright with right of publicity (which is what others are talking about here) - in this case, photographer can sue for copyright infringment, but only Marilyn's estate has a claim on the violation of right of publicity.
