<p>The usual way to include images in WordPress posts is to generate static anchor and <code><img></code> tags through the content editor interface. Similarly, links to other posts or pages of your blog are also generated as absolute <code><a></code> tags by the content editor.<br />
These kind of fixed links make your WordPress site hard to migrate and make it especially hard to automatically change your output markup (for instance if you decide to change the image size or change a post’s title).</p>
<p>No longer.<br />
With this plug-in, you can use the simple <code>[image]</code>, <code>[link]</code>, and <code>[page]</code> shortcodes in any of your posts.</p>
<h4>Image shortcode</h4>
<p>Images are referenced by their ID, for instance:</p>
<pre><code>[image id="123"]
</code></pre>
<p>This <em>shortcode</em> will generate the following HTML structure:</p>
<pre><code><div class="picture wp-image-123 size-medium">
  <img src="path-to-123-medium.jpg" srcset="…" />
</div>
</code></pre>
<p>Images default to their <code>medium</code> size, if none is set.<br />
You may easily add HTML classes or didascalies:</p>
<pre><code>[image id="123" didascaly="Nice picture." class="aligncenter"]
</code></pre>
<p>This generates the following HTML block, which can be easily styled with some custom CSS:</p>
<pre><code><div class="picture wp-image-123 size-medium aligncenter">
  <img src="path-to-123-medium.jpg" srcset="…" />
  <div class="didascaly">Nice picture.</div>
</div>
</code></pre>
<p>The <code>[image]</code> <em>shortcode</em> supports the following parameters:</p>
<ul>
<li><code>id</code>: the WordPress ID of the attachment to include;</li>
<li><code>size</code>: size of the image to include (can be any standard size such as <code>thumbnail</code>, <code>medium</code>, <code>full</code>, or any custom image size);</li>
<li><code>alt</code>: alternate description to include in the <code><img></code> tag;</li>
<li><code>title</code>: image title to use in (optional) link;</li>
<li><code>link</code>: if set to <code>true</code>, <code>1</code>, <code>yes</code>, or an equivalent value, a link to the full-resolution attachment will be generated, otherwise a fully specified target URL can be specified;</li>
<li><code>didascaly</code>: text to add as a didascaly;</li>
<li><code>class</code>: additional HTML/CSS classes to add to the root element.</li>
<li><code>atts</code>: additional HTML attributes to add to the wrapping <code><div></code> tag.</li>
<li><code>imgatts</code>: additional HTML attributes to add to the internal <code><img></code> tag of the image.</li>
</ul>
<h4>Page and link shortcodes</h4>
<p>This couple of <em>shortcodes</em> automatically generate hypertext links to pages or posts of your WordPress installation. Target posts can be referenced by ID, by <em>slug</em>, or by <em>path</em> (a post’s URL, relative to the website’s root).</p>
<p>Thus, <code>[link href="123"]…[/link]</code>, <code>[link href="slug-of-post"]…[/link]</code>, and <code>[link href="root-page/sub-page/slug-of-page"]…[/link]</code> are all equivalent.</p>
<p>These <em>shortcodes</em> are “enclosing” (they wrap the content of the link, just like HTML tags) and they support the following parameters:</p>
<ul>
<li><code>href</code>: the ID, <em>slug</em>, or <em>path</em> of the target post or page;</li>
<li><code>title</code>: the title to use in the link, if not set the target post’s title will be used;</li>
<li><code>class</code>: additional HTML/CSS classes to add to the link;</li>
<li><code>type</code>: type of the target post (defaults to “page” for <code>[page]</code> and “post” for <code>[link]</code>).</li>
</ul>
<p>If no link content to be enclosed is provided, the posts’s title is automatically used as link text.</p>


Simple Stupid Shortcode

The simplest and most flexible way to embed images or put internal links in Wordpress. Shortcodes to finally ditch all absolute paths and fixed sizes.

<p>Responsify WP is the WordPress plugin that cares about responsive images.</p>
<h3>Features</h3>
<ul>
<li>Use <code>img</code> with srcset/sizes attributes.</li>
<li>…or the <code>picture</code> element.</li>
<li>Works with or without <a href="http://scottjehl.github.io/picturefill/" rel="nofollow ugc">Picturefill</a>.</li>
<li>Supports high resolution images (retina).</li>
<li>Custom media queries.</li>
<li>Handpick which image sizes to use.</li>
<li>Responsive background images.</li>
</ul>
<h3><a href="https://www.youtube.com/watch?v=3ThYWO6vHKI&spfreload=10" rel="nofollow ugc">Demo</a></h3>
<p>Responsify WP finds featured images and all images inside the content and makes them responsive.<br />
For example, you might have a template that looks like this:</p>
<pre><code><article>
    <h1><?php the_title();?></h1>
    <?php the_content();?>
</article>
</code></pre>
<p>That will output something like this:</p>
<pre><code><article>
    <h1>Hello world</h1>
    <p>Lorem ipsum dolor sit amet...</p>
    <img src="large.jpg" alt="Image description">
</article>
</code></pre>
<p>But once you have activated the plugin, it will look like this instead:</p>
<pre><code><article>
    <h1>Hello world</h1>
    <p>Lorem ipsum dolor sit amet...</p>
    <img sizes="(min-width: 300px) 1024px, (min-width: 150x) 300px, 150px"
        srcset="thumbnail.jpg 150w,
        medium.jpg 300w,
        large.jpg 1024w"
        alt="Image description">
</article>
</code></pre>
<p>You can also choose to use the <code>picture</code> element instead:</p>
<pre><code><article>
    <h1>Hello world</h1>
    <p>Lorem ipsum dolor sit amet...</p>
    <picture>
        <source srcset="full-size.jpg" media="(min-width: 1024px)">
        <source srcset="large.jpg" media="(min-width: 300px)">
        <source srcset="medium.jpg" media="(min-width: 150px)">
        <img srcset="thumbnail.jpg" alt="Image description">
    </picture>
</article>
</code></pre>
<p>It also works with high resolution (retina) images:</p>
<pre><code><article>
    <h1>Hello world</h1>
    <p>Lorem ipsum dolor sit amet...</p>
    <picture>
        <source srcset="full-size.jpg" media="(min-width: 1024px)">
        <source srcset="large.jpg, large_retina.jpg 2x" media="(min-width: 300px)">
        <source srcset="medium.jpg, medium_retina.jpg 2x" media="(min-width: 150px)">
        <img srcset="thumbnail.jpg, thumbnail_retina.jpg 2x" alt="Image description">
    </picture>
</article>
</code></pre>
<p>The different versions of the image in the examples above is in the standard <code>thumbnail</code>, <code>medium</code>, <code>large</code> and <code>full</code> sizes.<br />
The <strong>media queries</strong> are based on the width of the “previous” image.<br />
Any <strong>custom sizes</strong> of the image will also be found and used.</p>
<h3>Settings</h3>
<p>You can <strong>select which image sizes</strong> that the plugin should use from the RWP settings page.<br />
These settings can be overwritten from your templates.</p>
<pre><code><?php

// Using get_posts()
$posts = get_posts( array(
    'post_type' => 'portfolio',
    'rwp_settings' => array(
        'sizes' => array('large', 'full')
    )
) );
foreach( $posts as $post ) {
    // ...
}

// Using WP_Query()
$query = new WP_Query( array(
    'category_name' => 'wordpress',
    'rwp_settings' => array(
        'sizes' => array('large', 'full')
    )
) );
if ( $query->have_posts() ) {
    // ...
}
?>
</code></pre>
<p><strong>Available settings:</strong></p>
<ul>
<li>Select which image sizes to use.</li>
<li>Set/override attributes.</li>
<li>Set custom media queries.</li>
<li>Turn on/off retina.</li>
<li>Ignore image formats.</li>
</ul>
<h3>Functions</h3>
<p>RWP provides a number of functions that can generate responsive images in your templates.<br />
Let’s say that you have the following markup for a very large header image:</p>
<pre><code><header>
    <?php the_post_thumbnail( 'full' ); ?>
</header>
</code></pre>
<p>As you probably know, <code>the_post_thumbnail()</code> will create a regular <code><img></code> tag with the full-size image in this case.<br />
But you don’t want to send a big 1440px image to a mobile device. This can easily be solved like this:</p>
<pre><code><header>
    <?php
    $thumbnail_id = get_post_thumbnail_id( $post->ID );

    // Generate an <img> tag with srcset/sizes attributes.
    echo rwp_img( $thumbnail_id );

    // Generate a <picture> element
    echo rwp_picture( $thumbnail_id );
    ?>
</header>
</code></pre>
