FSM Custom Featured Image Caption is a WordPress plugin that empowers users to add personalized captions to featured images in posts. Compatible with both Gutenberg and the classic editor, it allows for seamless integration of custom captions, which can replace the default captions from the Media Library. Users can choose to hide captions or the featured image entirely, and can also modify the caption's style settings to match their theme's design. The plugin includes a shortcode feature to display featured images with captions directly within post content, enhancing flexibility in presentation.

The latest version introduces experimental support for Divi themes, addressing user requests for compatibility. Although this feature may not work flawlessly for all layouts, it provides a new option for users looking to integrate custom captions into their Divi-based designs. Additional features include options for parsing HTML and shortcodes in captions, along with detailed settings for developers to customize output, ensuring broad usability and adaptability across various WordPress themes.
