If you would like to display multi-paragraph quotes with quotation marks as characters, rather than using images, you could use this;-

blockquote p::before {
  content: open-quote;
}

blockquote p::after {
  content: close-quote;
  visibility: hidden;
}

blockquote p:last-child::after {
  visibility: visible;
}

Of course, you can add indenting etc. as required.

Markup is simply;–

<blockquote>
  <p>paragraph one</p>
  <p>paragraph two</p>
  <p>paragraph three</p>
  <p>paragraph four</p>
</blockquote>

NB Only tested on Firefox.

Happy quoting.
