Author Image(s) Plugin

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:

1. 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.
2. 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.
3. 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.
4. 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).
5. 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.
6. 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.

• $after
  Optional argument. The text and/or HTML to appear after the author image/text, if any such text would be returned.

• $image_dir
  Optional argument. The directory, relative to the root of your blog, in which to find the author images. If not set, it defaults to the value configured via the plugin’s admin options page.

• $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.

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

• $author_id
  Optional argument. The id of the author. If null, then gets the author for the current post. Default is null.

• $args (as used in c2c_get_author_image())
  Optional argument. An array of configuration options.

  • author_id : default of current post author; the id of the author to get the image for
  • before : default of ”; text to show before each author
  • after : default of ”; text to show after each author
  • image_dir : default of ”; directory containing author images, relative to wp-content directory
  • width : default of ”; width to display image
  • height : default of ”; height to display image
  • show_name : default of ” which means it’ll abide by the plugin’s setting value; should the name of the author be shown in addition to the image?
  • show_fullname : default of false; should the user’s first and last name be shown instead of the author’s configured display name? (be sure to set ‘show_name’ to true if you want the name to appear in the first place)
  • show_name_if_no_image : default of ” which means it’ll abide by the plugin’s setting value; should the author’s name be shown if the author doesn’t have an image?
  • class : default of ”; array or string of classes to apply to author image tag
  • use_gravatar : default of plugin settings; should Gravatar be consulted for an author image if no local image for the author was found?

• $args (as used in c2c_wp_list_authors_images)
  Optional argument. An array of configuration options. All but the last two match up with the supported arguments of the wp_list_authors() function.

  • optioncount : default of false;
  • exclude_admin : default of true; should the admin user be excluded from the listing?
  • hide_empty : default of true; should authors who have not made any posts be excluded from the listings?
  • feed : default of ”
  • feed_image : default of ”
  • echo : default of true; should the listing be echoed to the page?
  • show_name : default of ” which means it’ll abide by the plugin’s setting value; should the name of the author be shown in addition to the image?

  • show_name_if_no_image : default of '' which means it’ll abide by the plugin’s setting value; should the author’s name be shown if the author doesn’t have an image?
  • before : default of ”; text to show before each author
  • after : default of ”; text to show after each author
  • image_dir : default of ”; directory containing author images, relative to wp-content directory
  • width : default of ”; width to display image
  • height : default of ”; height to display image
  • class : default of ”; array or string of classes to apply to author image tag

  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.

Arguments:

• same as for c2c_get_the_author_image()

Example:

Instead of:

 <?php $image = c2c_get_the_author_image(); ?> 

Do:

 <?php $image = apply_filters( 'c2c_get_the_author_image', ''); ?> 

c2c_the_author_image (action)

The ‘c2c_the_author_image’ hook allows you to use an alternative approach to safely invoke c2c_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.

Arguments:

• same as for c2c_the_author_image()

Example:

Instead of:

 <?php c2c_the_author_image( '<span class="author">', '</span>', '/images' ); ?> 

Do:

 <?php echo do_action( 'c2c_the_author_image', '<span class="author">', '</span>', '/images' ); ?> 

c2c_wp_list_authors_images (action)

The ‘c2c_wp_list_authors_images’ hook allows you to use an alternative approach to safely invoke c2c_wp_list_authors_images() 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_wp_list_authors_images()

Example:

Instead of:

 <?php echo c2c_wp_list_authors_images( array( 'hide_empty' => false ) ); ?> 

Do:

 <?php echo do_action( 'c2c_wp_list_authors_images', array( 'hide_empty' => false ) ); ?> 

1. Whether installing or updating, whether this plugin or any other, it is always advisable to back-up your data before starting
2. Unzip author-images.zip inside the /wp-content/plugins/ directory (or install via the built-in WordPress plugin installer)
3. Activate the plugin through the ‘Plugins’ admin menu in WordPress
4. Go to the Users -> Author Images admin options page. Optionally customize the options.
5. Create the directory(s) that will contain author image(s) (path must be relative to wp-content/ directory) (by default this would be /wp-content/images/authors/)
6. Put images into the specified image directory, using the author login name or the author ID as the filename,
   with whatever extension you plan to support, i.e. admin.gif or 1.gif
7. (optional) Use the provided “Author Image(s)” widget, if so inclined.
8. (optional) Modify your index.php and/or other template files to include calls to <?php c2c_the_author_image(); ?> and/or
   . (Read the rest of these notes for more info.)
9. (optional) Add the custom field ‘author_image’ to posts to explicitly define an image for the author for just that post. Otherwise, the plugin will proceed to attempt to find the author image.
10. (optional) Add the class “author_image” to your CSS file to control the display of the image located by c2c_the_author_image(), and/or add the class “list_author_image” to your CSS file to control the display of the images listed by c2c_wp_list_authors_images().

Where do I go to upload the author images?

Currently this plugin does not facilitate the uploading of images. It assumes you’ve already managed to get the author images onto your server into the appropriate directories.

Does this have a widget?

Yes, called “Author Image(s)”.
