Building
A building, or edifice, is a structure with a roof and walls standing more or less permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, and aesthetic reasons.

Image
An image (from Latin: imago) is an artifact that depicts visual perception, for example, a photo or a two-dimensional picture, that has a similar appearance to some subject—usually a physical object or a person, thus providing a depiction of it.

If you were to really hate and dislike a picture with all your heart, so that you could not bear to see or hear of it, how would you like it if someone insisted on getting to know and honor you through such a hated, horrible book? ... And God says that he does not like any image which we make, and ... that he hates and despises all who love images.
Andreas Karlstadt, On the Removal of Images (1522), p. 109

We require from buildings, as from men, two kinds of goodness: first, the doing their practical duty well: then that they be graceful and pleasing in doing it; which last is itself another form of duty.
John Ruskin, The Stones of Venice, Volume I, Chapter II.
