Start TYPO3 Responsive can extend tt_content elements images and images/text with a responsive lightbox feature.
This feature is based on the responsive framework Foundation.
Constant Editor > category: [START - TEMPLATES - IMAGE - FOUNDATION]
[X] Enable Lightbox: Images will rendered as clearing-thumbs
If you enable the lightbox property from above, the HTML of all images (tt_content) of the entire webiste will changed.
If you have any unexpected behaviour, please disable the lightbox property.
