# Images Don't Resize

### Regenerate Thumbnails

If you already uploaded images to media library, make sure you regenerate thumbnails by [following these steps.](/getting-started/usage.md)

### Low Server Resources

Resizing and trimming are resource-intensive tasks especially when processed images are large, make sure:

* In the plugin settings (under *WooCommerce menu → Smart Image Resize)*, select only sizes prefixed by **woocommerce\_** in the *Sizes* option.
* You increase server `memory_limit` to at least `512M`. (Recommended `1024M` )

### Purge Cache

Make sure you:

* clear your browser cache
* purge any caching plugin if present 
* purge CloudFlare cache if present

### Uploading Images Through WP REST API \[Advanced]

Images uploaded trough WP REST API using the route `/wp/v2/media`  are not resized by default. To enable it:

Add this code snippet to your theme **functions.php**:

```php
add_filter('wp_sir_process_media_library_upload', '__return_true');
```

or add this boolean parameter in your request `_processable_image` 

### Uploading Images Through WC Vendors Plugin

By default, images uploaded trough the frontend are not resized, to enable it, add this code snippet to your theme **functions.php**:

```php
add_filter('wp_sir_process_frontend_upload', '__return_true');
```
