Fcuk. I lost Post Thumbnails for 11000 posts.

Dont use it. Because this will delete your thumbnails. its check only images which is used in post content, not in _thumbnail. i use this plugin because i need to clean up disk space. i have over 11 thousand posts. over 6 thousand post i recently delete. so i need to delete all these images which was used on these 6 thousand post. its over 4 GB in size. so i could not take a backup. unfortunately all gone. all these 11 thousand posts now useless without thumbnail. so its totally mess for me. my work over months are wasted just for this fucking plugin.
