FBCacheView is a simple tool that scans your Web browser's cache (Internet Explorer, Firefox, or Chrome) and lists all images displayed on Facebook pages that you previously visited.
For every Facebook image, you will receive the following information: URL, the web browser used to visit the page, image type, date/time, visit time, image file size, and external URL (For images taken from another Web site).
FBCacheView doesn't require any installation process or additional DLL files. To start using it, run the executable file, and it scans the cache of your web browser and displays the list of all images loaded from Facebook Web pages. After a minute or two, you can view the picture in the lower pane of FBCacheView by selecting the desired item in the upper pane.
If FBCacheView fails to correctly detect your web browser's cache, you can go to the 'Advanced Options' window (F9) and choose the desired cache folders to scan for each Web browser.
