Display image (if present) and/or name for the author of a post, or for all authors on the blog.
Use <code><?php c2c_the_author_image(); ?></code> as a replacement for <code><?php the_author() ?></code> or <code><?php get_avatar(); ?></code> in index.php (and/or any other post templates) to display an image for a post’s author (inside “the loop”)
Use <code><?php c2c_wp_list_authors_images(); ?></code> as a replacement for <code><?php wp_list_authors(); ?></code> 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:
<ol>
<li>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.</li>
<li>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.</li>
<li>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.</li>
<li>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).</li>
<li>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.</li>
<li>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.</li>
</ol>
Additional notes:
<ul>
<li>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.</li>
<li>Images output by <code>c2c_the_author_image()</code> are defined with class=”author_image” for stylesheet manipulation</li>
<li>Images output by <code>c2c_wp_list_authors_images()</code> are defined with class=”list_author_image” for stylesheet manipulation</li>
</ul>
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.

<h3>Template Tags</h3>
The plugin provides three optional template tags for use in your theme templates.
<h4>Functions</h4>
<ul>
<li>
<code>function c2c_get_author_image( $args = array() )</code>

</li>
<li>
<code>function c2c_wp_list_authors_images( $args = '' )</code> 
A drop-in replacement for WordPress’s <code>wp_list_authors()</code>, allowing all authors for a blog to be listed with an image (if present).

<ul>
 false, ‘show_name_if_no_image’ => true)); ?>
</ul>
<h3>Filters</h3>
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.
</li>
</ul>
<h4>c2c_get_author_image (filter)</h4>
The ‘c2c_get_author_image’ hook allows you to use an alternative approach to safely invoke <code>c2c_get_author_image()</code> 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:
<ul>
<li>same as for <code>c2c_get_author_image()</code></li>
</ul>
Example:
Instead of:
<pre><code> <?php $image = c2c_get_author_image( array( 'show_name' => false ) ); ?>
</code></pre>
Do:
<pre><code> <?php $image = apply_filters( 'c2c_get_author_image', array( 'show_name' => false ) ); ?>
</code></pre>
<h4>c2c_get_the_author_image (filter)</h4>
The ‘c2c_get_the_author_image’ hook allows you to use an alternative approach to safely invoke <code>c2c_get_the_author_image()</code> 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.

</code></pre>
<h4>c2c_the_author_image (action)</h4>

</code></pre>
<h4>c2c_wp_list_authors_images (action)</h4>
The ‘c2c_wp_list_authors_images’ hook allows you to use an alternative approach to safely invoke <code>c2c_wp_list_authors_images()</code> 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.

Author Image(s)

Display image (if present) and/or name for the author of a post, or for all authors on the blog.

fmarzocca

Particularly suitable to all multi-nested categories and multi-authors website, with lots of posts and complex category layout (i.e.: academic papers, newpapers articles, etc), as weel as for single-user websites (read below). This plugin allows the user to place a shortcode into any page and get rid of a long and nested menu/submenu to show all site’s posts (including custom post types assigned to a standard category). A customizable selector in the page will allow the reader to select grouping by Category/Author/Title.
Shortcode’s options include:
<ul>
<li>excluding any category from the list</li>
<li>excluding/including admin users from the list</li>
<li>single-user website usage</li>
<li>select what list(s) to display</li>
<li>limit number of posts in list output </li>
<li>Show (optional) post date</li>
<li>Show in reverse date order</li>
</ul>
Output grouped by Category will look like:
<pre><code>CAT1
 post1 AUTHOR
 SUBCAT1
 post2 AUTHOR
 post3 AUTHOR
 SUBCAT2
 post4 AUTHOR
 ...
 ...
</code></pre>
Shortcode generator
The plugin installs a new menu ACT List Shortcodes in Admin->Tools. The tool is a helper to automatically generate the required shortcode. It will parse the options and display the string to be copied and pasted into any page. Please refer to the plugin admin page for a full list of options.
Default manual usage:
[ACT-list]
all categories and subcategories post, excluding administrator’s posts, grouped by (upon selection) Category/Author/Title
Exclude categories:
[ACT-list exclude=”cat1-slug, cat2-slug, …”]
listed categories will be excluded. Categories must be listed with their slugnames.
Include admin’s posts:
[ACT-list admin=1]
this option will also include all admin’s posts in the list.
Single-user website:
[ACT-list singleuser=1]
this option is suited for websites with a single author (or when you don’t want to show the authors). It removes grouping by Authors and any author name. This option includes the admin=1 option, so that it will list any post in the website. You can still apply “excluding categories” option.
Select what list(s) to display
The parameter “show” will allow the admin to select what lists will be shown and if the dropdown selector is needed or not. i.e.:
[ACT-list show=”Category, Author”]
or
[ACT-list show=”Title, Category”]
Allowed terms for the “show” parameter are: Author, Title, Category.
Split the lists into separate pages
By selecting only one variable in the “show” parameter, you will be able to show only one list without the dropdown selector. This will enable you to put the 3 lists into separate pages, or separate tabs of the same page.
Page#1 (or tab#1) 
[ACT-list show=”Category”]
Page#2 (or tab#2) 
[ACT-list show=”Author”]
Page#3 (or tab#3) 
[ACT-list show=”Title”]
Limit the number of posts in the lists
If you have a large numbers of posts (>2,000), it could be convenient to limit the number of posts in the lists, including only a certain amount of the most recent posts. This can be achieved separately for the 3 lists using the following parameters: postspercategory, postsperauthor, totalpoststitle. i.e.:
[ACT-list show=”Category” postspercategory=”20″] will show only the 20 most recent posts for each category.
Show posts list in reverse date order
By default, the posts will be listed from newest to oldest. To change this behaviour, use the reverse-date=1 parameter.
Show posts date (v.>=2.7.0)
The date of the post could be printed out before the post name, optionally
