LMDM Lightbox Image Caption

外掛說明

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.
