What is an imagery poem?

Imagery is figurative, collective mental pictures presented by a poet in his poems. They denote the eloquence of a poet in fewer Words and space. Poems of noted poets are rich in imagery. Alfred Lord Tennyson's The Lady Of Shalott is a fine example, in which exquisite images flow through our minds while we read the poem. It is the charm applied by the poet to captivate readers and audience. Tennyson is not alone in this faculty.
