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.
Source Code
The full source code, including the unminified JavaScript files, is included in the plugin directory under assets/js/.
Installation
- Upload the
smart-thumbnails-gwfolder to the/wp-content/plugins/directory. - Activate the plugin through the ‘Plugins’ menu in WordPress.
