 * Hey guys,
 * In the “Resize Images Larger” feature, it’s telling you that the new width should
   not be smaller than the width of your largest thumbnail, which is 3840px: [https://prnt.sc/49RCygKWUMwX](https://prnt.sc/49RCygKWUMwX)
   
   But I think 3840px is too big. I would like the maximum size to be 2000px wide.
   How do I change this?
 * Thank you!

 * Hi [@rodrigocs](https://wordpress.org/support/users/rodrigocs/)
 * It looks like you have 3840px thumbnail registered (maybe by your theme, some
   other plugin or you changed default WP thumbnail sizes).
 * Our [Remove Thumbnail Sizes plugin](https://github.com/wp-media/imagify-helpers/raw/master/various/imagify-remove-thumbnail-sizes/imagify-remove-thumbnail-sizes.zip)
   should be able to deregister any thumbnail sizes that you don’t want, but you’ll
   likely need to customize it based on the specific thumbnails that you wish to
   deregister.
 * To start, go to your Imagify plugin settings page and view the files optimization
   section to see all the thumbnail sizes currently registered with your site.
 * Record the names of all the thumbnails that you want to deregister.
 * Here are the steps to take once you have all the names recorded:
 * 1) Unzip the helper plugin zip file and open the PHP file in a text editor. This
   is the part of the code that you can edit, the rest should stay untoucvhed:
 *     ```
       $thumb_names = array(
       	// EDIT_HERE
       	'1536x1536',
       	'2048x2048'
       	// STOP_EDITING
       );
       ```
   
 * For each of the thumbnail names that you recorded, you will need to add a new
   line. These new lines of code should be identical to the line above it, except
   that you will substitute the thumbnail name, and the last value you add should
   not end with a comma.
 * So for example, if you were trying to deregister the “post-thumbnail” and “twentytwenty-
   fullscreen” thumbnails, your code would be as follows:
 *     ```
       $thumb_names = array(
       	// EDIT_HERE
       	'1536x1536',
       	'2048x2048',
       	'post-thumbnail',
       	'twentytwenty-fullscreen'
       	// STOP_EDITING
       );
       ```
   
 * 2) Once this is complete, save the PHP file and zip it back up into a .zip file.
 * 3) Install and activate this updated helper plugin through your WordPress Admin
   plugins page.
 * 4) Check to make sure the target sizes have been removed from the Files Optimization
   section in your Imagify plugin settings page, and the thumbnail sizes should 
   be deregistered. Those thumbnails won’t be created for any new images you upload.
 * Note: This plugin deregisters thumbnail sizes so they won’t be generated when
   you upload new images to your Media Library, but this will not remove thumbnails
   that are already on your server.
 * Hope this helps. ​Let me know if you need any further assistance, I am happy 
   to help.
 * Best Regards
