Responsify WP

Descripción

Responsify WP is the WordPress plugin that cares about responsive images.

Funcionalidades

  • Use img with srcset/sizes attributes.
  • …or the picture element.
  • Works with or without Picturefill.
  • Supports high resolution images (retina).
  • Custom media queries.
  • Handpick which image sizes to use.
  • Responsive background images.

Demo

Responsify WP finds featured images and all images inside the content and makes them responsive.
For example, you might have a template that looks like this:

<article>
    <h1><?php the_title();?></h1>
    <?php the_content();?>
</article>

That will output something like this:

<article>
    <h1>Hello world</h1>
    <p>Lorem ipsum dolor sit amet...</p>
    <img src="large.jpg" alt="Image description">
</article>

But once you have activated the plugin, it will look like this instead:

<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>

You can also choose to use the picture element instead:

<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>

It also works with high resolution (retina) images:

<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>

The different versions of the image in the examples above is in the standard thumbnail, medium, large and full sizes.
The media queries are based on the width of the “previous” image.
Any custom sizes of the image will also be found and used.

Configurar

You can select which image sizes that the plugin should use from the RWP settings page.
These settings can be overwritten from your templates.

<?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() ) {
    // ...
}
?>

Available settings:

  • Select which image sizes to use.
  • Set/override attributes.
  • Set custom media queries.
  • Turn on/off retina.
  • Ignore image formats.

Functions

RWP provides a number of functions that can generate responsive images in your templates.
Let’s say that you have the following markup for a very large header image:

<header>
    <?php the_post_thumbnail( 'full' ); ?>
</header>

As you probably know, the_post_thumbnail() will create a regular <img> tag with the full-size image in this case.
But you don’t want to send a big 1440px image to a mobile device. This can easily be solved like this:

<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>

Reseñas

Fantastic

This Plugin accomplished, what all others failed to do: make my images responsive, which was blocked by my theme’s developer (Grand Photography by Theemegoods). From what I’ve seen, support is outstanding and doens’t leave anything to be desired.

Best plugin and more than perfect support

I had many problems and many of theese were because I’m not an informatic expert.
I received help for everyone of theese.
The support team is very patient and helpfull to solve every problem I had.

I advice the plugin to averyone.

Best Of Its Kind

I tried many different plugins before i found this one, and it’s easily the best of the bunch. It allowed me to add srcset to all the images on my website which wasn’t done by default with my theme. As other reviewers have said, the plugin author is very helpful and definitely lives up to the claim that Responsify WP cares about responsive images!

Still useful after WordPress 4.4 and SUPERB support!

The current WordPress responsive image implementation only inserts srcsets for your images when the aspect ratio differs by less than 0.002.

If you wish to insert srcsets where the images’ aspect ratios differ by greater than 0.002, this plugin is a must! If you theme already creates a ton of image sizes and you don’t want to waste them this plugin is for you.

The rwp_add_filters filter with the included snippet in the documentation allows you to apply the srcsets to images used by other plugins and widgets.

Further, the author provides fantastic support on the forums – bugs are fixed quick.

This is a great plugin with great support!
