Description

Format the Nivo output for attached images

Extract from Nivo's documentation

• To add a caption to an image you simply need to add a title attribute to the image.
• To add an HTML Caption simply set the title attribute to the ID of a element that contains your caption (prefixed with a hash).
• Note that the HTML element that contains your caption must have the CSS class nivo-html-caption applied and must be outside of the slider div.

The HTML caption logic was implemented in version 1.12, using oik's format= parameter. Since there can be multiple sliders on a page the unique ID in the title attribute needs to take into account the slider instance (slider-id). The hyphen between the slider-id and post id helps ensure uniqueness. Added support for link=full, in addition to link=file. link=full will open the link to the original image link=file opens the links to the image of the selected thumbnail size

Usage

bw_format_nivo_attachment( $post, $atts );

Parameters

$post

( post ) required – the post to be displayed

$atts

( array ) required – array of parameters; name value pairs

Returns
