Someone asked me if they may have a mezuza on their door since it is facing another door with a tzelem hanging on it and it might not be proper kavod to the mezuza.
I think that it is allowed if it is covered (i.e. that you cannot see the Sh-Ka-i (Hashem's name) on the parchment). Although the tzelem is considered as (at least safek Avodah Zarah)idolatry (Yoreh Deah 141:1 Rema and Shach ibid:6), still it should be similar to the halacha that one must cover ervah infront of a Sefer Torah, tefillin, sefarim or mezuzas etc... (Mishna Berura 240:27 etc...). It is required kli betoch kli. Perhaps the case is similar to a mezuza in front of tinuf (Yoreh Deah 286:5) where the shulchan Aruch writes only " tov lichasost hamezuza" - (which is more lenient) provided there is no ervah.
In any case would a plastic non translucent case with a ש printed on it work? (I believe that some rabbonim say it is fine for kli betoch kli, although I do not understand the reasoning for this, since the case is designated for the mezuzah).
I believe some Rabonim require a cloth or the like to cover the mezuza (on top of the case), it makes sense halachikly speaking, however it does not seem to be the main practiced view. I would appreciate your help on these questions.
