  1. POmy custom made php/jquery gallery lightbox won't centre as page loads
    text
    copied!<p>I created a custom gallery and it works perfectly in internet explorer however in firefox and chrome it doesn't work like it should. The lightbox doesn't pop up on the clicking the thumbnail link, you have to click it twice, when clicked once the backdrop comes up but not the lightbox, but then on clicking the thumbnail twice it centers and pops up. And I have no clue why, please help.</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
