<h4>iSlidex is a WordPress slideshow plugin that will display images taken from posts in a specific category.</h4>
Completely automated once you set the number of slides you would like to feature, the size and the category from where iSlidex will pull the images from. 
You can decide also whether to have nice semi-transparent captions, with the title of the post for each slide. 
iSlidex comes with a widget, which can be set independently from the main slider, from the same settings page, however we do recommend the use of the plugin only inside big sidebars, in order to be displayed in the best way. 
Every image is resized and cached automatically, and you dont have to worry about server load or manual image editing. 
Also, we optimized the code for better SEO, so that every image has its alt and titles attributes and we have added compatibility with qTranslate plugin. 
Islidex also comes with different slideshow themes to choose from!
Cross-browser compliant: Internet Explorer 7, Internet Explorer 8, FireFox 3+, Safari 4+, Chrome 4+, Opera 10+.
WordPress 3.1+ compatible.
<h4>Can I use it in a post/page to display only the images from that post/page?</h4>
NO! 
iSlidex is specifically built only to display 1 image per each post from a set category, not all the images in 1 post. We are thiking about adding this in the future, no need to request it.
<h4>Problems making it work?</h4>
If you can’t make the plugin work, check out the Usage instructions and FAQ, ask in the forums so we can help you, instead of reporting it as broken.

Note: You probably do not need this plugin. The REST API already supports adding the query param <code>?_embed</code> to your URL and the response will then include all “embedded media”, including the featured image, and the data you get there is exactly what this plugin gives you. The only reasons to use this plugin at this point are if you prefer to have the featured image data in a top level field in the response rather than among other embedded media in the <code>_embedded</code> field, and if you always want the featured image data in the response rather than having to ask for it with <code>?_embed</code>. I still use this plugin because I do usually want both these things, but definitely give <code>?_embed</code> a try before using this plugin. 🙂
Version 2 of the WordPress REST API returns a <code>featured_media</code> field (formerly featured_image) on the post object by default, but this field is simply the image ID.
This plugin adds a <code>better_featured_image</code> field to the post object that contains the available image sizes and urls, allowing you to get this information without making a second request.
It takes this:
<pre><code>"featured_media": 13,
</code></pre>
And turns it into this:
<pre><code>"featured_media": 13,
"better_featured_image": {
 "id": 13,
 "alt_text": "Hot Air Balloons",
 "caption": "The event featured hot air balloon rides",
 "description": "The hot air balloons from the big event",

The format of the response is nearly identical to what you would get sending a request to <code>/wp-json/wp/v2/media/13</code> or using <code>?_embed</code>. When no featured image has been set on the post the <code>better_featured_image</code> field will have a value of <code>null</code>.
I’ve done some basic performance tests that indicate the difference in response times with and without this plugin to be about 10-15ms for a collection of 10 posts and 0-5ms for a single post. For me this is much faster than making a second request to <code>/media/</code>, especially for multiple posts.
As of version 1.1.0, there is a filter <code>better_rest_api_featured_image</code> that allows you to add custom data to the better_featured_image field. The filter is directly on the return value of the function that returns the better_featured_image field. This can be used to do things like add custom image meta or an SVG version of the image to the response. Here’s an example of how you might use it:
<pre><code>add_filter( 'better_rest_api_featured_image', 'xxx_modify_rest_api_featured_image', 10, 2 );
/**
 * Modify the Better REST API Featured Image response.
 *
 * @param array $featured_image The array of image data.
 * @param int $image_id The image ID.
 *
 * @return array The modified image data.
 */
function xxx_modify_rest_api_featured_image( $featured_image, $image_id ) {

 // Add an extra_data_string field with a string value.
 $featured_image['extra_data_string'] = 'A custom value.';

 // Add an extra_data_array field with an array value.
 $featured_image['extra_data_array'] = array(
 'custom_key' => 'A custom value.',
 );

 return $featured_image;
}
</code></pre>

Better REST API Featured Images

Does what id says, and it helps me a lot while building the theme in Angular2. Only one GET to have Post and Featured Image details!



Perfect! Must be in the API core

The Plugin works very well and saves time, thanks!



Works also with REST API V2

Thanks Martin.
This plugin does excectly what is says it would do.
And this should definitely be integrated in the main api code!!!



Great plugin, why is this not in the default API?

Awesome

Adds a top-level field with featured image data including available sizes and URLs to the post object returned by the REST API.
