<p>With <strong>GIC</strong>, you can display the title, caption, and description image attributes. You can also change/filter the rendering HTML to whatever you want.</p>
<p>After installing and activating GIC, write your filter and add the WordPress <a href="https://codex.wordpress.org/Gallery_Shortcode" rel="nofollow ugc">Gallery shortcode</a> to your page.</p>
<p>If you’ve been <em>dreaming</em> of writing a filter to customise the gallery image captions, then this plugin is for you.</p>
<p><a href="https://streetphotography.blog/gallery-image-captions-demo/" rel="nofollow ugc">Visit the live demo page.</a></p>
<h4>Motivation</h4>
<p>The default WordPress gallery shortcode will only display the <strong>caption</strong> from the media’s attachment metadata. Sometimes it’s nice to display more like the title—even the description.</p>
<p>The <strong>GIC plugin</strong> overrides the WordPress gallery shortcode function to create a <a href="https://developer.wordpress.org/plugins/hooks/" rel="nofollow ugc">hook</a>. With this <em>hook</em> you can do a little bit more than just displaying the caption.</p>
<p>Some premium themes hide the caption completely. This leaves photography lovers like me scratching their head and spending precious time cobbling together makeshift caption blocks.</p>
<h3>Usage</h3>
<h4>Custom Filter For Displaying Captions</h4>
<p>The <strong>crux</strong> of this plugin is the ability to filter the gallery image caption. The <code>galimgcaps_gallery_image_caption</code> hook makes this possible.</p>
<p>For the usage examples below, this is the filter used.</p>
<pre><code>/**
 * Custom Filter for Gallery Image Captions
 *
 * Note: Avoid altering captiontag, selector, and itemtag.
 */
function mlc_gallery_image_caption($attachment_id, $captiontag, $selector, $itemtag) {

    $id = $attachment_id;

    // Grab the meta from the GIC plugin.
    $my_image_meta = galimgcaps_get_image_meta($id);

    /**
     * Here's where to customise the caption content.
     * 
     * This example uses the meta title, caption, and description. 
     * 
     * You can display any value from the $my_image_meta array. 
     * You can add your own HTML too.
     */
    return "<{$captiontag} class='wp-caption-text gallery-caption' id='{$selector}-{$id}'>" .
            "Title: " . $my_image_meta['title'] . "<br>" .
            "Caption: " . $my_image_meta['caption'] . "<br>". 
            "Description: ". $my_image_meta['description'] . 
        "</{$captiontag}></{$itemtag}>";

}
add_filter('galimgcaps_gallery_image_caption', 'mlc_gallery_image_caption', 10, 4);
</code></pre>
<p>Feel free to use this filter code as a starter template. After activating the GIC plugin, add the code above to your child theme’s <code>functions.php</code> file. Rename the function and tweak the return string to suit your needs.</p>
<h4>New Filter To Get Custom Fields</h4>
<pre><code>/**
 * New GIC 1.4.0 filter for custom meta fields.
 */
function gic_add_custom_fields( $image_meta, $attachment ) {

    // This is how you add a custom fields to the array that
    // GIC uses to display captions.
    $image_meta['credit_text'] = $attachment->credit_text;
    $image_meta['credit_link'] = $attachment->credit_link;

    return $image_meta;
}
add_filter( 'galimgcaps_image_meta', 'gic_add_custom_fields', 10, 2 );
</code></pre>
<p>To use these two custom fields, your <code>galimgcaps_gallery_image_caption</code> would look something like this.</p>
<pre><code>function mlc_gallery_image_caption($attachment_id, $captiontag, $selector, $itemtag) {

    $id = $attachment_id;

    // Grab the meta from the GIC plugin.
    $my_image_meta = galimgcaps_get_image_meta($id);

    // If there's credit, give it where it's due complete with link.
    $credit = $my_image_meta['description'] ? 
        "<br><strong>Credit</strong>: <a style='display: inline;' href='" . 
        $my_image_meta['credit_link'] . 
        "'>" . $my_image_meta['credit_text'] . "</a>" . "<br>" : 
        '';

    /**
     * With GIC 1.4.0 you can also add custom media attachment fields
     * to your captions.
     */
    return "<{$captiontag} class='wp-caption-text gallery-caption' id='{$selector}-{$id}'>" .
            "<strong>Caption</strong>: " . $my_image_meta['caption'] . "<br>" . 
            $credit .
            "</{$captiontag}></{$itemtag}>";

}
add_filter('galimgcaps_gallery_image_caption', 'mlc_gallery_image_caption', 10, 4);
</code></pre>
<p><strong>Since v1.2.0</strong>, GIC automatically adds an <strong>Image ID</strong> column to your WordPress Media Library. This is to help you add the image IDs to your GIC shortcodes.</p>

<p><strong>New in v1.4.0</strong>, GIC support custom media attachment fields.</p>
<h3>Usage Example 1</h3>
<h4>Shortcode</h4>
<p>For starters, let’s use a</p>
<pre><code><p></p> 
</code></pre>
<p>tag for the caption tag.</p>
<pre><code>[gallery size="full" columns="1" link="file" ids="114" captiontag="p"]
</code></pre>
<h4>Styling</h4>
<p>Let’s override the generated styles with our own style for one particular image.</p>
<pre><code>/* Targeting a Specific Image */

/* Add some padding all around. */
#gallery-1 .gallery-item, 
#gallery-1 .gallery-item p {
    padding: 1%;
}

/* Add some moody background with typewriter font. */
#gallery-1 .gallery-item {
    color: whitesmoke;
    background-color: black;
    font-size: 1.25rem;
    font-family: Courier, monospace;
    text-align: left !important;
}
</code></pre>
<h3>Usage Example 2</h3>
<h4>Shortcode</h4>
<p><strong>A 2 column x 1 row gallery with large size images using an H4 for the caption.</strong></p>
<pre><code>[gallery size="large" columns="2" link="file" ids="109,106" captiontag="h4"]
</code></pre>
<p><strong>A 3 column x 1 row gallery with medium size images using a blockquote for the caption.</strong></p>
<pre><code>[gallery size="medium" columns="3" link="file" ids="109,106,108" captiontag="blockquote"]
</code></pre>
<p>Did you notice that we are using</p>
<pre><code><blockquote></blockquote> 
</code></pre>
<p>in the second shortcode? Let’s give it try just for <em>kicks</em>.</p>
<h4>Styling</h4>
<pre><code>/* 1. Style the H4 Used in the Caption Example */
h4 {
    color: #777777 !important;
    font-size: 1.2rem !important;
    font-family: Helvetica, Arial, sans-serif !important;
}

/* 2. Help Align the Blockquote */
#gallery-3 .gallery-caption {
    margin-left: 40px !important;
}
</code></pre>
<h3>Responsive CSS Example</h3>
<p>I recommend adding the following media queries if you use galleries with more than one image. The two media queries below will stack 2×1 and 3×1 galleries into a 1 column x n rows or 2 column x n rows  as needed.</p>
<pre><code>/* Media Queries for Responsive Galleries */

/**
 * Styling based on article "How To: Style Your WordPress Gallery"
 * by Par Nicolas.
 * 
 * https://theme.fm/how-to-style-your-wordpress-gallery/
 */

/* Mobile Portrait Breakpoint - 1 column */
@media only screen and (max-width: 719.998px) {
    .gallery-columns-2 .gallery-item,
    .gallery-columns-3 .gallery-item { 
     width: 100% !important; 
  }
}

/* Mobile Landscape and Tablet Breakpoints - 2 columns */
@media only screen and (min-width: 720px) and (max-width: 1024px) {
  .gallery-columns-3 .gallery-item { 
     width: 50% !important; 
  }
}
</code></pre>

Black Studio

<p>This plugin adds a new <code>Visual Editor</code> widget type that allows you to insert rich text and media objects in your sidebars with no hassle. With Black Studio TinyMCE Widget you will be able to edit your widgets in a WYSIWYG manner using the native WordPress TinyMCE editor, just like you do in posts and pages. And if you are a developer you may still switch back and forth from Visual to HTML mode.</p>
<p>For years the default WordPress text widget has been very basic and it required HTML knowledge to add formatting and images/media to the text. This plugin was born in 2011 to overcome these limitations. After a long time, in June 2017, version 4.8 of WordPress finally introduced a new text widget that included the ability to manage text widgets with the visual editor. The new widget available in WordPress core could now be used as a basic replacement of Black Studio TinyMCE Widget, but the plugin still offers some additional features, so it remains a must-have for advanced users.</p>
<h4>Basic Features</h4>
<ul>
<li>Add rich text widgets to your sidebars and edit them using the TinyMCE visual editor</li>
<li>Switch between Visual mode and HTML mode (including Quicktags toolbar)</li>
<li>Insert images, videos, and other media from WordPress Media Library</li>
<li>Insert links to existing WordPress pages/posts or external resources</li>
<li>Support for shortcodes, smilies and embed in widget text (including preview)</li>
<li>Support for the Block-based Widgets Editor introduced with WordPress 5.8</li>
<li>Support for Customizer with live preview and quick edit</li>
<li>Support for widgets accessibility mode</li>
<li>Compatible with multi-site (WordPress networks)</li>
<li>Compatible with the most common multi-language plugins</li>
<li>Compatible with Page Builder plugin by SiteOrigin</li>
<li>Translations available in 20+ languages</li>
</ul>
<h4>Advanced Features</h4>
<p>These features are what makes this plugin better than the WordPress (4.8+) native widget:</p>
<ul>
<li>Full featured TinyMCE Visual Editor (the same you have for pages and posts)</li>
<li>Wide text area for an enhanced editing experience</li>
<li>Compatible with 3rd party TinyMCE customization plugins (TinyMCE Advanced, WP Edit, …)</li>
<li>Support for distraction-free (fullscreen) editing mode </li>
<li>Option to “Automatically add paragraphs” to widget text</li>
</ul>
<h4>About the plugin</h4>
<p>The story of the plugin was featured in a talk at WordCamp Europe 2018 in Belgrade.<br />
