## Description

**Are you tired of WordPress creating dozens of unused thumbnail sizes for every
image you upload?**

By default, WordPress and many themes register multiple image sizes and generate
them for _every single upload_, filling your server with thousands of files you 
will never use. This wastes disk space and makes managing your media library difficult.

**Smart Thumbnails GW solves this problem.**

This plugin stops WordPress from creating unnecessary files and gives you precise
control. Its intelligent logic generates custom sizes **only for Featured Images**
when a post is saved. Images uploaded into your post content won’t create any extra
thumbnails, saving you valuable server space.

Control exactly which sizes are created for each post type (posts, pages, products,
etc.), clean up unused images automatically, and regenerate thumbnails only when
you need to.

## Installation

 1. Upload the `smart-thumbnails-gw` folder to the `/wp-content/plugins/` directory.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.
 3. Go to **Settings -> Smart Thumbnails** to configure the plugin and define your 
    custom image sizes.

## FAQ

### I defined a new size. Why aren’t my old featured images showing it?

You need to regenerate thumbnails for existing images. Go to the plugin’s settings
page, click on the “Regenerate Thumbnails” tab, select the post type, and start 
the regeneration process.

### Will this plugin create sizes for images I upload to the post content?

No. To save server space, this plugin is designed to create custom sizes _only_ 
for **Featured Images**. Images uploaded to the content area will not have custom
sizes generated.

### Can I define sizes for images uploaded directly to the Media Library?

Yes. In the “Image Sizes” tab, you will see a post type called “Media” (`attachment`).
Any sizes you define there will be created for images uploaded directly to the Media
Library.
