Disable thumbnail sizes, default WordPress sizes and theme/plugins image size and others image advanced control.
Useful for disable some unused image sizes from WooCommerce, theme or plugins. This can be a good choice for decrease images generated and them space.
Smart Initialization: The plugin intelligently imports current WordPress settings (from themes, other plugins, or custom functions.php) rather than using default values. This maximizes compatibility with existing sites and ensures smooth integration without disrupting current configurations.
Important: From the moment of installation, the plugin takes control of the settings. Any external overrides (from themes, other plugins, or custom code) will be clearly indicated in red warnings below the settings, allowing you to identify and resolve conflicts.

Why should I disable thumbnail sizes?
Every size WordPress generates takes up space on your server. If your theme only uses two or three sizes, the rest are just wasted storage. Disabling them means faster uploads and less disk usage.
Do I need to regenerate thumbnails after changing settings?
Yes. Changes only apply to new uploads. To update existing images, use a plugin like Regenerate Thumbnails or run wp media regenerate from WP-CLI.
What does “Disable Threshold” do exactly?
Since WordPress 5.3, any image wider or taller than 2560 px is automatically scaled down and the original is saved with a -scaled suffix. Disabling the threshold keeps your originals untouched. You can also set a custom value (e.g. 4000 px) instead of disabling it entirely.
What happens if another plugin also sets JPEG quality?
The plugin compares your setting against the WordPress default (82%) and shows an info message below the field. Since 0.7.0 the conflict detection is safer and won’t interfere with other plugins.
Is this plugin compatible with WooCommerce?
Yes. WooCommerce registers its own image sizes and they’ll appear in the Image Sizes list so you can disable them individually.
Does the plugin affect the front end?
The settings pages are admin-only. The only thing that runs on the front end is a lightweight filter registration (no database queries) that tells WordPress which sizes to skip and what quality/threshold to use.
