I love the JJ NextGen JQuery Slider plugin, but it does cause validation errors in HTML5 and XHTML 1.0 Strict, and a simple change to the plugin alleviates this problem.
By simply replacing the deprecated border="0" attribute the plugin generates for each slider image with an alt="slider" attribute, the plugin no longer breaks validation and still works perfectly in all the major browsers.
Could the dev integrate this minor fix into future versions of the plugin so I don't have to keep hacking the /includes/jj_ngg_jquery_slider.php file (line 226) to keep this fantastic plugin from breaking validation on my websites? Validation is not my ultimate goal in life, but I try to keep from violating standards needlessly.
