WordPress.org

Display an image for each category associated with a post.

Notes:

This plugin provides the templates tag c2c_the_category_image() which basically reproduces and extends the functionality of WordPress's core function the_category() to add the ability to display a category image instead of the category name in the link to the category archive. With its $image_extensions argument defaulted to "", the plugin could be a drop-in replacement for the_category(). As is done in the_category(), the image or text for each category is also a link back to that category's archive.

Related info about the function:

• If $image_extensions is defined, but no image is found for the category, then nothing is displayed for that category.
• $image_extensions can be defined as a space separated list of image extensions. Files will be checked with the image extensions in the order those extensions were provided; default is 'png gif jpg'.
• The number of category links/images displayed can be limited via the $limit argument
• Category image tags are defined with class="catimage" for stylesheet manipulation.
• The result can be filtered via the filter named "c2c_the_category_image".
• Must be run inside "the loop".

c2c_get_category_image_list()

is another provided function, which is identical to c2c_the_category_image() except that it doesn't echo the result.
