-- Identify and remove orphan **product images** (reading data from media_gallery).
+- Identify and remove orphan **product images** (reading data from media_gallery) and **product images cache**.
 - Identify and remove orphan **WYSIWYG images and files** (reading used images/files from cms_block, cms_page, core_email_template tables and all /skin/frontend CSS files).
