This plugin is ment mostly for developers. You need to use its functions in your theme or plugin to make it works.
This plugin offers functionality like face detection crop, focal point selector for every image, function to output responsive <picture> sizes and more.
<h3>Why to use this plugin?</h3>
WordPress will automatically create a lot of smaller images for every uploaded image. 
You mostly need just 1 or 2 of them, so this is a waste of your server space and resources. 
Also cropped images are generated from the center by default, which can be a problem many times.
This plugin allows you to:
<ul>
<li>disable autogenerated image sizes</li>
<li>dynamically generate only needed image sizes for only needed images</li>
<li>delete generated image sizes from this plugin individually or all together</li>
<li>specify different focal point that will be in the focus while creating cropped versions of the image</li>
<li>automatically detect focal point by face detection algorithm</li>
<li>disable big image size threshold, so image bigger than 2560x2560px will be NOT scaled down</li>
</ul>
<h3>How it works</h3>
<ol>
<li>if you disable existing autogenerated image sizes, then newly uploaded images will not create its sizes</li>
<li>you need to specify in your code what size is needed for the image</li>
<li>image is dynamically created on the first visit of the page and is stored in <code>uploads</code> folder</li>
<li>every next visit of that page will just load already generated image</li>
</ol>
<h3>Functions</h3>
bis_get_attachment_image_src( $attachment_id, $size, $crop )
Function inspired by default <code>wp_get_attachment_image_src</code>. 
If you used Fly Dynamic Image Resizer before, you don’t need to replace <code>fly_get_attachment_image_src</code> functions in your code – there is a fallback, so you can deactivate Fly Dynamic Image Resizer and it will still work.
Parameters:
<ul>
<li>
attachment_id (integer)(required) 
The ID of the image attachment 
Example: <code>123</code> or <code>get_post_thumbnail_id()</code> or <code>get_field('my_image')</code>
</li>
<li>
size (array)(required) 
An array with the width and height 
Example: <code>[ 1920, 1080 ]</code>
</li>
<li>
crop (boolean/integer/array/string)(optional) 
Skip this or pass <code>false</code> or <code>0</code> if you don’t want to crop, just rescale, 
otherwise pass <code>true</code> or <code>1</code> to use focal point crop that is selected in admin media (by default center), 
or pass array with string x-axis and y-axis parameters like <code>[ 'right', 'bottom' ]</code> 
or pass array with numeric x-axis and y-axis parameters like <code>[ 0.5, 0.8 ]</code> 
or pass string <code>'face'</code> to automatically detect face position (can be exhaustive on server resources)
</li>
</ul>
Returns:
<pre><code>array(
 'src' => (string) url of the image,
 'width' => (integer) width in pixels,
 'height' => (integer) height in pixels
)
</code></pre>

<li>
attachment_id (integer)(required) 
The ID of the image attachment 
Example: <code>123</code> or <code>get_post_thumbnail_id()</code> or <code>get_field('my_image')</code>

</li>
</ul>

</code></pre>
 
<h3>There is no fallback for <code>fly_add_image_size</code> function</h3>
If you used Fly Dynamic Image Resizer before, you need to remove <code>fly_add_image_size</code> functions from your code. 
You can create your own variables for sizes if you need it, like
<pre><code>define( 'MY_CUSTOM_SIZE', [ 1000, 200 ] );
</code></pre>
and then just us it inside functions, like:
<pre><code>echo bis_get_attachment_image( get_post_thumbnail_id(), MY_CUSTOM_SIZE );
</code></pre>
 
<h3>Support other extensions than JPG, PNG and WEBP</h3>
This plugin works by default only with JPG, PNG and WEBP files, 
but you can easily allow any other mime types, 
just use this code eg. in <code>wp-config.php</code> or in your <code>functions.php</code>
<pre><code>define( 'BIS_ALLOWED_MIME_TYPES', array( 'image/jpeg', 'image/png', 'any_other/mime_type' ) );
</code></pre>
 
<h3>Get selected image focal point</h3>
Focal point data are stored in the attachement post metas. 
There is also custom sanitize function, that you can use.
<pre><code>$focal_point = sanitize_focal_point( get_post_meta( get_post_thumbnail_id(), 'focal_point', true ) );
</code></pre>
Returns:
<pre><code>array( 0.5, 0.8 )
</code></pre>
which means that focal point is 50% from left and 80% from top

Better image sizes


Great plugin. It lets you cut out all the random image sizes (and their file bloat) so you can just make the image sizes you actually need. One of the first plugins I install for every build. 



I'm so thankful to the developer for carrying on the legacy of the deprecated "Fly Images" plugin.


Fantastic

Dynamically generate only needed image sizes for only needed images, with manually selected focal point for crops
