This hack makes Wordpress display a category image next to posts.

Every category needs to have an *.png image named in accordance to the "nice name" of the category (if the category is called "Web Development", the nice name would be "web-development" so the category image should be "web-development.png" and placed in the /wp-images folder in the root of a Wordpress blog).

A "my-hacks.php" file must exist on the server of a Wordpress installation. If one does not exist create one. Also, ensure that the "Use legacy my-hacks.php file support" checkbox is checked in Options > Miscellaneous in the admin area of wordpress.
