Remove a directory permanently from git

Question

In my personal git repo, I have a directory that contains thousands of small images that are no longer needed. Is there a way to delete them from the entire git history? I h

The ProGit book has an interesting section on Removing Object.

It does end with this:

Your history no longer contains a reference to that file.
However, your reflog and a new set of refs that Git added when you did the filter-branch under .git/refs/original still do, so you have to remove them and then repack the database. You need to get rid of anything that has a pointer to those old commits before you repack:

$ rm -Rf .git/refs/original
$ rm -Rf .git/logs/
$ git gc
$ git prune --expire 

(git prune --expire is not mandatory but can remove the directory content from the loose objects)
Backup everything before doing those commands, just in case ;)
