Alt tag interfering with slideshow

[jem08002]

The slideshow generates thumbnails that can not be edited, therefore an alt tag cannot be added for these specific thumbnails/filmstrips.

They sent me the following code which will need some tweaking:

function metaslider_filmstrip_alt_tags( $list_item, $post, $url ) {$alt = get_post_meta( $post->ID, '_wp_attachment_image_alt', true );$list_item = "
ID} post-{$post->ID}" style="display: none;">"{$alt}"";return $list_item;}
add_filter( 'metaslider_filmstrip_list_item', 'metaslider_filmstrip_alt_tags', 10, 3 );
