The Site Title Caption Modifier is a simple WordPress plugin that sets the caption of all images in your WordPress site to the site title. This is particularly useful for maintaining a consistent branding or style across all posts and pages. The plugin works by hooking into the WordPress ‘img_caption_shortcode’ filter and modifying the caption output.

FoA Featured Image – Show Caption is a simple WordPress plugin that extends the core Featured Image block with caption functionality. When enabled, it displays the image caption (or title if no caption exists) below the featured image.
Key Features:
<ul>
<li>Adds a “Show Caption” checkbox setting to the Featured Image block</li>
<li>Displays the image caption (or title if no caption) below the featured image</li>
<li>Works with the Gutenberg block editor and templates</li>
<li>Clean, minimal styling that works with most themes</li>
<li>Right-aligned caption with light grey color</li>
</ul>
How it Works:
<ul>
<li>The plugin extends the core Featured Image block with additional settings</li>
<li>When “Show Caption” is enabled, it checks for a caption on the featured image</li>
<li>If no caption exists, it falls back to using the image title</li>
<li>The caption is displayed in a <code><div class="featured-image-caption"></code> element</li>
<li>Works with both regular posts/pages and WordPress templates</li>
</ul>
Styling:
The plugin includes default CSS styling for the caption: 
* Text aligned to the right 
* Light grey color (#999) 
* Italic font style 
* Small font size
You can easily customize the appearance by targeting the <code>.featured-image-caption</code> class in your theme’s CSS. The plugin uses standard CSS specificity, so your theme styles will override the defaults.
