I’m trying drupal 6.x from some weeks ago. On Drupal 5.x, I’ve used Greybox Redux module to display HTML content on a Javascript popup window. On 6.x, where Greybox isn’t available, I try successfully Lightbox v2. I use this module for images on many sites: syntax to display HTML on a popup IFRAME changes slightly:

<a rel="lightframe" http="http://example.com" title="Lightframe label">Link Text</a>

And this is the l() equivalent:

l('Link text', 'http://example.com', array('attributes' => array('rel'=>'lightframe', 'title'=>'"Lightframe label')))

You can also use the grouping feature to browse prev/next elements:

'rel'=>'lightframe[mygroup]'

customize display style:

'rel'=>'lightframe[|width: 800px; height: 600px;]'

both:

'rel'=>'lightframe[mygroup|width: 800px; height: 600px;]'

Complete example:

l('Link text', 'http://example.com', array('attributes' => array('rel'=>'lightframe[mygroup|width: 800px; height: 600px;]', 'title'=>'"Lightframe label')))

• Comparison of “lightbox” type modules

Prerequisites:

• inline module
• lightbox2 module
• imagecache module

You simply enable lightbox v2 on image nodes (admin/settings/lightbox2) but your lightbox show a small imagecache thumbnail?

• Disable lightbox on image nodes (admin/settings/lightbox2)
• Enable “Display image with a link to the image file” (admin/settings/inline)
• Apply this Inline lightbox patch

This patch simply add a rel=”lightbox” to each inline image link, natively pointing to full-size image.
