Here‘s the site.
I contained the “Caption” button in a div and I’m trying to figure out how to position it relative to the image, just under it. So when I change the image, it positions itself just under the new image too. However, I can’t even get it to position relative to the image. Here’s the code:
<?php
$username = $_GET['username'];
session_start();
$_SESSION['username'] = $username;
//Database Information
$dbhost = "";
$dbname = "";
$dbuser = "";
$dbpass = "";
//Connect to database
mysql_connect ( $dbhost, $dbuser, $dbpass)or die("Could not connect: ".mysql_error());
mysql_select_db($dbname) or die(mysql_error());
//Do the query
$query = mysql_query("SELECT * FROM images ORDER BY idnum DESC LIMIT 5");
//Generate an array of all images
$images = array();
while($image = mysql_fetch_array($query)) {
//this adds each image to the images array
$images[] = $image;
$image['filename'] = $firstimage;
}
?>
<?php
// Beginning attempt at a caption script.
?>

<script type="text/javascript">
// Switches the url to view large image.
function switchImageUrl(url, width, height) {
var x = document.getElementById('caption_selection');
x.style.display = 'none';
document.getElementById('center_frame').style.backgroundImage = 'url' + '(' + url + ')';
document.getElementById('center_frame').style.width = width;
document.getElementById('center_frame').style.height = height;
}
</script>
<script type="text/javascript">
function selectionToggle() {
var x = document.getElementById('caption_selection');
if(x.style.display == 'block')
x.style.display = 'none';
else
x.style.display = 'block';
x.style.width = '75px';
x.style.height = '75px';
x.style.top = '0px';
x.style.left = '0px';
}

<?php echo $image['name']." - by ".$image['submitter']; ?> <br/>
<br/>
<?php } ?>
</div>

<div id="center_frame" style="width: <?php echo $image['width']; echo "px" ?>; height: <?php echo $image['height']; echo "px" ?>; background-image: url('<?php echo $image['filename'];?>')" >

I’m not sure where it’s being set (probably styles.css), but change the positioning style for the ‘#center_frame’ element from absolute to relative. That appears to fix the problem.
