Juxtaposition - Analogy

Analogy is the comparison of two pairs which have the same relationship. The key is to ascertain the relationship between the first so you can choose the correct second pair.

Analogy is divided into Metaphor and Simile.

Metaphor: a metaphor is the expression of an understanding of one concept in terms of another concept, where there is some similarity or correlation between the two.
Example: Boy, am I burned up!

Simile: a figure of speech in which two unlike things are explicitly compared.
Example: He was like a cock who thought the sun had risen to hear him crow.

I was surfing on the internet and found a few interesting photos taken by some unknown photogtaphers. those photos clearly shows what Juxtaposition is.
