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.

Jetpack has a pretty robust Image slideshow feature. (If you don’t know, “Add Media” button > “Create Gallery” > Choose photos > “Create new gallery” > Change type to slideshow in “Gallery Settings” > “Insert Gallery”)
Make sure you have “Compose using shortcodes to embed media from popular sites” enabled in “Settings” > “Writing” > Composing section of Jetpack settings.
Jetpack’s handling of photo’s captions doesn’t work well with long captions (as it overlays the caption above the photo). This plugin modifies the layout so that the caption is displayed below the photo and the slideshow expands to accommodate.
