## Descripción

**Warning: _Crazy Lazy_ has reached end of life. WordPress 5.5+ supports [lazy-loading of images in Core](https://make.wordpress.org/core/2020/07/14/lazy-loading-images-in-5-5/)
based on the native HTML `loading` attribute. If you look for an alternative plugin,
we recommend to use [Lazy Loader](https://wordpress.org/plugins/lazy-loading-responsive-images/)
instead.**

_Crazy Lazy_ helps increasing the performance of your blog or website by displaying
images efficiently. When a page would usually display some images, _Crazy Lazy_ 
will prevent those images to load. Only when a user scrolls down the page and reaches
the position where an image actually should be displayed, that particular image 
will be loaded from the server.

By loading images only when needed, _Crazy Lazy_ will reducing page loading times
and (potentially costly) traffic.

This Lazy Load plugin is structured very lean and does not require any settings:
activate, done. Depending on the theme or the usage of jQuery _Crazy Lazy_ optionally
will utilze a modified version of the jQuery plugin [Unveil.js](https://github.com/luis-almeida/unveil),
or the native JavaScript library [lazyload.js](https://gist.github.com/miloplacencia/3931803).

### Styling

Placeholders for images can be styled, i.e. like this:

    ```
    img[src*='data:image/gif;base64'] {
        border: 1px dashed #dbdbdb;
    }

    img.crazy_lazy {
        background: url(/wp-includes/images/wpspin-2x.gif) no-repeat center center;
        background-size: 16px 16px;
    }
    ```

### Excluding images

It’s possible to exclude some images from the lazy loading. This can be achieved
by adding a data attribute `data-crazy-lazy="exclude"` or `data-skip-lazy` to the
images that should not lazy loaded by the plugin.
 Alternatively you can add a CSS
class `crazy_lazy` or `skip-lazy`. These CSS classes can also be added to the image
block.

## FAQ

### Will this plugin lazy load all the images on a page?

All images that have been uploaded into your media library, including featured images.

### Will I have to edit any theme template files to make this work?

Usually no. If Crazy Lazy doesn’t work out of the box, check your active theme’s`
footer.php` template file. There should be a line calling `wp_footer()` in it which
is required for Crazy Lazy to work properly.

### Will Crazy Lazy work well with any caching plugins?

Crazy Lazy will work with every caching plugin, including our own [Cachify](https://wordpress.org/plugins/cachify/).
