Plugin Description
Display image (if present) and/or name for the author of a post, or for all authors on the blog.
Use <?php c2c_the_author_image(); ?> as a replacement for <?php the_author() ?> or <?php get_avatar(); ?> in index.php (and/or any other post templates) to display an image for a post’s author (inside “the loop”)
Use <?php c2c_wp_list_authors_images(); ?> as a replacement for <?php wp_list_authors(); ?> in the sidebar section of your site to list all authors for the blog using an image and/or text.
The plugin also provides a simple widget for listing authors.
Process by which the image is located and/or text used:
- If a post has an ‘author_image’ custom field defined, the plugin checks if the value is the valid name of an image in the defined image directory. If not, it appends each of the defined image extensions, in turn, to the custom field’s value, then checks if an image can be found.
- If no image has been found yet, it looks in the image directory for a file with a name that is the author’s login name with a file extension matching one of the ones defined in image extensions.
- If no image has been found yet, it looks in the image directory for a file with a name that is the author’s ID with a file extension matching one of the ones defined in image extensions.
- If no image has been found yet and Gravatar support is enabled, it then asks Gravatar for the avatar associated with the author (based on author’s email address).
- If no image has been found yet and a blank/generic image has been defined, then the blank image is used as the author’s avatar.
- If an image has been found and the “Show author name as well?” setting is true, or if no author image has been found and “Show author name if image is found?” setting is true, then the author’s name is appended/used.
Additional notes:
- The plugins admin options page allows you to control if the author’s name should appear alongside the author image or not, if the author name should be shown in the event no author image could be found, the image directory, the support image extensions, and if and what you want the author image to link to.
- Images output by
c2c_the_author_image() are defined with class=”author_image” for stylesheet manipulation
- Images output by
c2c_wp_list_authors_images() are defined with class=”list_author_image” for stylesheet manipulation
Tip:: You can take advantage of the $image_dir argument to display different author images under different contexts, i.e. locate your images in different directories ‘wp-content/images/authors/small/’ and ‘wp-content/images/authors/large/’ and decide on context where to get the image(s) from.

Template Tags
The plugin provides three optional template tags for use in your theme templates.
Functions
-
function c2c_get_author_image( $args = array() )
Gets the image and/or name for an author.
-
function c2c_the_author_image( $before = '', $after = '', $image_dir = '', $width = '', $height = '' )
A drop-in replacement for WordPress’s the_author() , allowing the author for the post to have an image displayed in lieu of the name (if an image can be found).
-
function c2c_wp_list_authors_images( $args = '' )
A drop-in replacement for WordPress’s wp_list_authors(), allowing all authors for a blog to be listed with an image (if present).
This displays the image associated with a post’s categories.
Arguments
-
$before
Optional argument. The text and/or HTML to appear before the author image/text, if any such text would be returned.

-
$width
Optional argument. The forced width of the image (will cause browser to resize if image is of different width). Leave blank to retain image’s original width (or for the width to be scaled in proportion to a specified height). It is recommended that images exist at the desired size.
-

false, ‘show_name_if_no_image’ => true)); ?>
Filters
The plugin exposes two filters and two actions for hooking. Typically, customizations utilizing these hooks would be put into your active theme’s functions.php file, or used by another plugin.
c2c_get_author_image (filter)
The ‘c2c_get_author_image’ hook allows you to use an alternative approach to safely invoke c2c_get_author_image() in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site.
Arguments:
- same as for
c2c_get_author_image()
Example:
Instead of:
<?php $image = c2c_get_author_image( array( 'show_name' => false ) ); ?>
Do:
<?php $image = apply_filters( 'c2c_get_author_image', array( 'show_name' => false ) ); ?>
c2c_get_the_author_image (filter)
The ‘c2c_get_the_author_image’ hook allows you to use an alternative approach to safely invoke c2c_get_the_author_image() in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site.

c2c_the_author_image (action)

- same as for
c2c_the_author_image()
Example:
