1) Script Title: Advanced Gallery script

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex17/agallery.htm

3) Describe problem: I want to use this script, but I need the images to be centered on the page. Could you please tell me what to change/add to get the images to be centered since the images now appear on the left?

I searched the forums but I can't find a fix that will work for this script. If I missed a post, could you please let me know.

Thanks in advance.

Add the highlighted in the codes:


<style type="text/css">

.gallerycontroller{
width: 250px;
margin:1px auto; /*top right bottom left margin */
}

.gallerycontent{
width: 250px;
height: 200px;
border: 1px solid black;
background-color: #DFDFFF;
padding: 3px;
display: block;
margin:1px auto; /*top right bottom left margin */
}

</style>

<script type="text/javascript">

To make this work in IE, add a DTD (http://www.w3.org/TR/html401/sgml/dtd.html). Try adding this above the <html> tag:


<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">


See if it helps ;)
