Here's a quote by Howard W Hunter about posting a picture of the temple in your home:

"Let us be a temple-attending and a temple-loving people. Let us hasten to the temple as frequently as time and means and personal circumstances allow. Let us go not only for our kindred dead, but let us also go for the personal blessing of temple worship, for the sanctity and safety which is provided within those hallowed and consecrated walls. The temple is a place of beauty, it is a place of revelation, it is a place of peace. It is the house of the Lord. It is holy unto the Lord. It should be holy unto us.

"Let us share with our children the spiritual feelings we have in the temple. And let us teach them more earnestly and more comfortably the things we can appropriately say about the purposes of the house of the Lord. Keep a picture of a temple in your home that your children may see it. Teach them about the purposes of the house of the Lord. Have them plan from their earliest years to go there and to remain worthy of that blessing."
