Time saver, extremely useful

Thank you very much for this helpful plugin. The plugin is very useful if thumbnail sizes change with a theme change or similar (especially if the site has a great number of images). It’s only one click to delete all thumbnails and another to regenerate new thumbnails. I really hope the developer won’t be discouraged by the one star ratings from users who are not able to cope with site specific problems. Nobody should rate one star without asking for help first. Thank you very much for this great plugin, which saved me a lot of time and helped to clean up server space by removing thumbnails that are not used anymore.
