Descripción
WordPress ships with a native Lightbox-Effect for image blocks. This plugin adds one tiny additional option to the core image and gallery blocks: Show Caption.
When the toggle is enabled, the native lightbox receives the current image alt text as a data-img-alt attribute on the enlarged lightbox figure. A small frontend CSS then displays that value as a caption overlay inside the lightbox image.
Please note: The caption text is taken from the image alt attribute.
The toggle is only available when the native Lightbox-Effect is active. If the lightbox is disabled or the image is linked somewhere else, the caption option is disabled as well.

FAQ
-
Does it create a new block?
-
No, it only extends the existing core Image and Gallery blocks.
-
Does it use the normal image caption field?
-
No. It uses the image
altattribute and writes it todata-img-altin the native lightbox overlay. -
Why is the toggle disabled?
-
The toggle is only active when the native WordPress Lightbox-Effect is enabled. If the image links to a media file, attachment page or custom URL, the native lightbox is not active and the option is disabled.
-
Does it work with galleries?
-
Yes. Enable the native Lightbox-Effect for the gallery first and then enable
Show caption. The setting is passed to the gallery images when the block is rendered. -
Does it load any additional assets in the frontend?
-
Yes, it loads one small CSS file that displays the
data-img-altvalue as a pseudo element in the native lightbox overlay. -
What happens when i disable the plugin?
-
The additional toggle and frontend caption output disappear. Existing Image and Gallery blocks continue to work as normal core blocks.
