Muslim mosques are richly decorated, but not one design must look anything like a flower or bird or person. An exception to this is allowed in Iran where flower decorations are viewed as acceptable. Similarly some of the Puritans after the Reformation used the second commandment to destroy priceless stained glass windows and statues. But most Christians think the point of the second commandment is not to prohibit art, imagery, book illustrations, Sunday School pictures, etc. The purpose of the absolute prohibition of idolatry is to prevent us making a stereotype, and limiting God to that form and locality.
Idolatry is of course a great guilt producer.
The result is that any idol soon becomes a vicious guilt producer. Which is why the prohibition of the second commandment is an absolute. The opposite of prostrating ourselves before an idol is the carefree love of a little child chattering and singing with a loving parent. That still leaves us with the responsibility of working at the dividing line between idolatrous worship and the use of pictures in Sunday School.
