TV Output ModX Revolution

So I have a chunk:

<li> [[+img-port]]
          <div class="floater">
            <h2>[[+longtitle]]</h2>
            <p>[[+introtext]]</p>
            <p class="readmore"><a href="[[~[[+id]]]]" title="Read more</a></p>
          </div>
        </li>

And a TV-parameter "img-port" input: image, output: image. I've selected an image for every my document. But when I place a chunk into my webpage everythig is fine, but Image. I see lo开发者_高级运维ngtitle, introtex, but Image.

Is this a getResources template chunk? Then you have to enable TV processing with "&processTVs=1" (see docs).

Can you inspect the rendered HTML using Firebug or just even "View Source". Is there possible a problem with the image path?
