Image title attribute

Perhaps this could help?

Thanks @kerec. I already have a similar javascript solution in place. I’m hoping for a way to do it without the JS setting. The title and alt should be different in most cases. Right now I have to use my alt like a title. Hoping to avoid that.

With JS, perhaps you could create your titles from custom attributes, a bit like here, only setting the attr ?

Not sure if it help, but I would use the “cleaner_gallery_image” filter to add the image title attribute:

/* Filter the gallery images with user options. */
add_filter( 'cleaner_gallery_image', 'lw_add_title_tag_image', 10, 2 );

/**
 * Filters the gallery image if it has a link and adds the appropriate attributes for the lightbox
 * scripts.
 *
 * @since  0.9.0
 * @access public
 * @param  string  $image
 * @param  int     $id - the attachment ID
 * @param  array   $attr
 * @param  int     $instance
 * @return string
 */
function lw_add_title_tag_image( $image, $id ) {

	$attachment_title = get_the_title($id);
	$image = str_replace( '<img ', '<img title="' . $attachment_title . '" ' , $image );

	return $image;
}

Thanks @landwire. That looks like it should work. The str_replace isn’t my favorite method, but it would accomplish the goal. Thanks for sharing.
