Efficiently Regenerate Thumbnails via CLI
Avoid PHP timeouts and memory errors by processing image resizing directly on the server using WP-CLI. Ideal for large media libraries.

Useful Flags
--yes Skip Confirmation
Automatically answer "yes" to the confirmation prompt. Essential for automated scripts or cron jobs.
--only-missing Optimize Processing
Only regenerate thumbnails for images that are missing sizes. Skips images that are already correct. Great for fixing broken imports.
--image_size=medium Target Specific Size
Only regenerate a specific image size (e.g., 'thumbnail', 'medium', 'large'). Saves CPU time if you just added a new custom size.
