<p>This plugin behaves similarly to <a href="https://wordpress.org/plugins/regenerate-thumbnails/" rel="ugc">Regenerate Thumbnails</a> except that images are resized automatically / on the fly, when they are used. Once created, they won’t be processed again.</p>
<p>Your thumbnails will now resize when:</p>
<ul>
<li>Image Sizes in <strong>Settings > Media</strong> is modified,</li>
<li>Switching themes & plugins with different thumbnail / featured image sizes</li>
</ul>
<p>No settings pages, just install and activate and things should work right away.</p>
<p>Report bugs and help out in the code from the <a href="https://github.com/gambitph/WP-OTF-Regenerate-Thumbnails" rel="nofollow ugc">Github repository</a></p>
<h4>What are you talking about?</h4>
<p>Test it out. In your normal WordPress website set up, create a gallery using the <strong>Add Media</strong> button while editing a post or page and use thumbnails. Afterwards, check out your gallery.</p>
<p>Notice the size of your thumbnails, most likely they’re <strong>150 x 150</strong>. Do you see it? Great.</p>
<p>Now head over to <strong>Settings > Media</strong> and change your thumbnail size to something cooler, something rectangular, let’s try <strong>400 x 200</strong>. Save it.</p>
<p>Go back to your gallery that you previously created and refresh your browser. Most likely you <em>won’t</em> be seeing <strong>400 x 200</strong> thumbnails there.</p>
<p>OTF Regenerate Thumbnails fixes this for you.</p>
<h4>Usage</h4>
<p>OTF Regenerate Thumbnails should work right away, and your images should get resized when the dimensions get changed.</p>
<p><strong>For developers & tinkerers, ensuring your images get resized properly requires you to use WordPress’ image functions to display featured images and image attachments.</strong> Don’t worry, this is a good thing.</p>
<p>Make sure you use these WordPress functions <strong>every time you display images</strong>:</p>
<ul>
<li><a href="https://codex.wordpress.org/Function_Reference/wp_get_attachment_image_src" rel="nofollow ugc"><code>wp_get_attachment_image_src</code></a></li>
<li><a href="https://codex.wordpress.org/Function_Reference/wp_get_attachment_image" rel="nofollow ugc"><code>wp_get_attachment_image</code></a></li>
<li><a href="https://codex.wordpress.org/Function_Reference/the_post_thumbnail" rel="nofollow ugc"><code>the_post_thumbnail</code></a></li>
<li><a href="https://codex.wordpress.org/Function_Reference/get_the_post_thumbnail" rel="nofollow ugc"><code>get_the_post_thumbnail</code></a></li>
</ul>
<p>You can also add size <em>names</em> using <a href="https://codex.wordpress.org/Function_Reference/add_image_size" rel="nofollow ugc"><code>add_image_size</code></a></p>
<h4>Features</h4>
<ul>
<li>Creates Resizes thumbnails on the fly</li>
<li>Handles Image Size settings changes in <strong>Settings > Media</strong></li>
<li>Handles thumbnail / image size changes introduced by switching themes & plugins</li>
<li>Works automatically, no setup needed</li>
<li>All calls to <code>the_post_thumbnail</code> and other thumbnail functions are handled automatically</li>
<li>Handles image sizes created from <code>add_image_size</code>,</li>
<li>Handles <a href="https://codex.wordpress.org/Function_Reference/the_post_thumbnail" rel="nofollow ugc">2-item array sizes</a></li>
</ul>

<p>Image Regenerate & Select Crop plugin provides enhanced control over image settings and files regeneration, allowing you to override native medium and large crop options, and register new sub-sizes. The plugin appends additional buttons to regenerate and crop images (providing detailed information about the registered image sub-sizes and their status within the application) and enables configuration of the plugin for global or specific post-type attached images.<br />
For the latest updates and detailed feature descriptions, visit <a href="https://iuliacazan.ro/image-regenerate-select-crop/" rel="nofollow ugc">https://iuliacazan.ro/image-regenerate-select-crop/</a>.</p>
<h4>Key Features</h4>
<ul>
<li>Details button: opens a lightbox displaying detailed information on any missing sub-size files and options for manual generation if applicable. For crop-type images, the plugin offers the one-click re-crop option, using specific portions of the original image with an instant preview feature.</li>
<li>Regenerate button: allows one-click regeneration of all image sizes for a specific image, ensuring that all uploaded images are updated with the newly registered sizes.</li>
<li>Raw cleanup button: allows you to delete all files and metadata for the attachment, keeping only the original file and information, so you can easily regenerate afterward only the desired sub-sizes.</li>
<li>The plugin integrates seamlessly without requiring additional code, adding the buttons to the “Edit Media” page, as well as “Edit Post” and “Edit Page” sections where a featured image is present, and in the image block. It is compatible with custom post types (including WooCommerce products) and supports various resolutions and responsive layouts.</li>
</ul>

Image Regenerate & Select Crop


I'm astounded by how well thought out and comprehensive this plug-in is in engaging the problems it intends to solve. Huzzah!


Pretty Amazing


to view article preview images nicely. i use YARPP to view the related images.Problem the blog post images are width and the bigger preview images 150px+ are not cropped anymore.



So i created 400 x 200 px new preview related posts with this plugin.


Nice to add own size and crop

Advanced management for images, register new sub-sizes, sub-sizes details, regenerate and cleanup files.
