NextGEN Smooth Gallery Slideshow W3C fix

There is a simple change that can be made to keep your page XHTML 1.0 Transitional when using the NextGEN Smooth Gallery Slideshow.

In the file:
/wp-content/plugins/nextgen-smooth-gallery/nggSmoothSharedFunctions.php

Change line 183 & 184. The image tag is missing the alt declaration, this adds alt=”the image title”.

The old lines are:

183     $out .= "  <img src=\"" . $picture["img"]   . "\" class=\"full\" />";
184     $out .= "  <img src=\"" . $picture["thumb"] . "\" class=\"thumbnail\" />";

The new lines should be (line numbers are not to be considered as code):

183     $out .= "  <img src=\"" . $picture["img"]   . "\" class=\"full\" alt=\"" . $picture["title"] . "\" />";
184     $out .= "  <img src=\"" . $picture["thumb"] . "\" class=\"thumbnail\" alt=\"" . $picture["title"] . "\" />";
