Hi,
You can do this with our Images gallery element and use custom links as on click action
But there is no nofollow attribute for them. You will need to modify the file woodmart/inc/shortcodes/images-gallery.php and replace this line
<a href="<?php echo esc_url( $link ); ?>" data-index="<?php echo esc_attr( $i ); ?>" data-width="<?php echo esc_attr( $width ); ?>" data-height="<?php echo esc_attr( $height ); ?>" <?php if( $target_blank ): ?>target="_blank"<?php endif; ?> <?php if( $caption ): ?>title="<?php echo esc_attr( $title ); ?>"<?php endif; ?>>
with this one
<a href="<?php echo esc_url( $link ); ?>" data-index="<?php echo esc_attr( $i ); ?>" data-width="<?php echo esc_attr( $width ); ?>" data-height="<?php echo esc_attr( $height ); ?>" <?php if( $target_blank ): ?>target="_blank"<?php endif; ?> <?php if( $caption ): ?>title="<?php echo esc_attr( $title ); ?>"<?php endif; ?> rel="nofollow">
