Plugin URI: http://devcorner.georgievi.net/wp-plugins/wp-category-icons/
Category Icons is a plugin that makes it possible to assign icons to categories.

===== FEATURES =====

The plugin has the following features:
* User can assign or clear icons to categories through admin panel.
* Directory and URL for icons can be specified thorugh admin panel. Upload options can be used instead.
* A template tag (function) is exposed to include category icon into templates.
* Plugint installs itself, by creating a database table and setting default option values, when activated.

===== INSTALLATION =====

Copy the category_icons.php file into your wp_content/plugins directory.
Activate the plugin from Plugins admin menu. 

Once the plugin is activated it creates a "Cat Icons" panel under "Options".
This will allow you to manage category icons.

===== USAGE =====

The plugin exposes the get_cat_icon function as WordPress template tag to be used in 
WordPress templates. It takes following options, passed in WordPress template tags style:
   - fit_width - maximum width of image. -1 for do not care. Default is -1
   - fit_height - maximum height of image. -1 for do not care. Default is -1
   - exapnd - Expand image to fit the rectangle if smaller? Default "false".
   - cat - Category ID. Default is current category.
   - small - Is this a small icon? Default "false"

Examples:

This example will insert the icon associated with the current category:
    <?php get_cat_icon(); ?>
    
This example inserts icon for the category with ID '5'. The image is fitted withing rectangle 100x100.
If the image is smaller than desired, it is expanded.:
    <?php get_cat_icon('cat=5&fit_width=100&height=100&expand=true'); ?>

Спасибо огромное, sonika!
Я как раз искал какой-нибудь плагин, но почему-то ничего достойного не находил.
Единственное, я ещё до конца не понял, как им правильно пользоваться, не было времени разобраться 🙁
Установить – установил, в опциях он появился, я даже могу выбрать, из каких папок и с каким расширением ему подцеплять файлы, но сделать привязку конкретной картинки к конкретной категории пока что ещё не получилось.

А Вы поищите в англоязычной части интернета, может на форумах http://wordpress.org/support/ обсуждали этот плагин.
Я сама его не ставила.

Выяснил, что если на 2.0.4 плагин работает, то на 2.1 (на который мне, собственно, и надо поставить Category Icons) возможности привязать категорию к картинке нет 🙁 А ещё и разработчик вместе с сайтом куда-то пропал, незадача!

а еще бы не помешала иконка в названии поста %)
