-##&lt;iron-image&gt;
-
-`iron-image` is an element for displaying an image that provides useful sizing and
-preloading options not found on the standard `<img>` tag.
-
-The `sizing` option allows the image to be either cropped (`cover`) or
-letterboxed (`contain`) to fill a fixed user-size placed on the element.
-
-The `preload` option prevents the browser from rendering the image until the
-image is fully loaded.  In the interim, either the element's CSS `background-color`
-can be be used as the placeholder, or the `placeholder` property can be
-set to a URL (preferably a data-URI, for instant rendering) for an
-placeholder image.
-
-The `fade` option (only valid when `preload` is set) will cause the placeholder
-image/color to be faded out once the image is rendered.
-
-Examples:
-
-  Basically identical to `<img src="...">` tag:
-
-```html
-<iron-image src="http://lorempixel.com/400/400"></iron-image>
-```
-
-  Will letterbox the image to fit:
-
-```html
-<iron-image style="width:400px; height:400px;" sizing="contain"
-  src="http://lorempixel.com/600/400"></iron-image>
-```
-
-  Will crop the image to fit:
-
-```html
-<iron-image style="width:400px; height:400px;" sizing="cover"
-  src="http://lorempixel.com/600/400"></iron-image>
-```
-
-  Will show light-gray background until the image loads:
-
-```html
-<iron-image style="width:400px; height:400px; background-color: lightgray;"
-  sizing="cover" preload src="http://lorempixel.com/600/400"></iron-image>
-```
-
-  Will show a base-64 encoded placeholder image until the image loads:
-
-```html
-<iron-image style="width:400px; height:400px;" placeholder="data:image/gif;base64,..."
-  sizing="cover" preload src="http://lorempixel.com/600/400"></iron-image>
-```
-
-  Will fade the light-gray background out once the image is loaded:
-
-```html
-<iron-image style="width:400px; height:400px; background-color: lightgray;"
-  sizing="cover" preload fade src="http://lorempixel.com/600/400"></iron-image>
-```
