   hi viper,
   regenerate thumbnail is a great plugin and it helps big time in my project. However, i need to delete the delete the old thumbnails, which are previously generated.
   we change our theme often and according to our needs the thumbnail size would also be changed(drastically), so i need to delete the old thumbnail images previously generated using the plugin.
   currently i do it manually by accessing my cpanel, is their any other way to do it.

   Regenerate Thumbnails - Version 2.2.0

   In file regenerate-thumbnails.php locate this, at line 357:
   

   @set_time_limit( 900 ); // 5 minutes per image should be PLENTY
   
   $metadata = wp_generate_attachment_metadata( $image->ID, $fullsizepath );

   Add this block of code between the two lines:
   

   @set_time_limit( 900 ); // 5 minutes per image should be PLENTY
   
   // find and delete any previous image-sizes
   $info = pathinfo($fullsizepath);
   $ext = $info['extension'];
   $pattern = str_replace(".$ext", "-*x*.$ext", $fullsizepath);
   foreach (glob($pattern) as $filename) {
   	@unlink($filename);
   }
   
   $metadata = wp_generate_attachment_metadata( $image->ID, $fullsizepath );

   This will delete any previously generated image-sizes, including older outdated sizes before creating the new sizes.

   Important: Note that URLs to images are hard-coded in posts and pages. Removing old thumbnails could result in broken images if they are still used somewhere on your site. You have been warned...
