Jews are strictly forbidden to worship any idols or images, even those of G-d itself, and in a stricter sense, it is even forbidden to look at those idols or images of worship of others. This is the principal reason why Jews are forbidden to enter Christian churches, those with imagery of G-d, Jesus, saints, etcetera, are considered idolatry. The first two portions of the ten commandments as given to Moses at Sinai explicitly says;

“You shall have no other gods before Me. You shall not make for yourself a graven image, nor any manner of likeness of anything that is in heaven above, that is in the earth beneath, or that is in the water under the earth. You shall not bow down to them, nor serve them. For I the L‑rd your G‑d am a jealous G‑d, visiting the iniquity of the fathers upon the children of the third and fourth generation of them that hate Me; and showing mercy unto the thousandth generation of them that love Me and keep My commandments.”

You won’t find depictions of G-d in any actual Jewish book, you will not find these things in a Jewish home, in all branches of Judaism, idol worship and graven imagery are strictly forbidden. As an artist, I once created paintings of angels and gods of other religions, it was my money maker and I was an occultist back then, now, I don’t and instead paint nature and Jewish imagery and artworks. Of the ten commandments, this is one that is often broken with no regard but is no less a serious offense to G-d as any other.

This is a commandment the Jewish people take very seriously, not unlike those of the Muslim faith, which consequently is one of the reasons Jews can enter mosques and pray to HaShem, but not churches (also due to having one god and not a trinity).
