    <p>i have a simple tag based image gallery which saves all images in a database. To show these images there is a small php script</p> <pre><code>&lt;?php include_once("config/config.php"); $mysql_user = USER; $password = PWD; $database_host = HOST; $database = DB; mysql_connect($database_host, $mysql_user, $password) or die ("Unable to connect to DB server. Error: ".mysql_error()); mysql_select_db($database); header('Content-type: image/jpeg'); $query = "SELECT imgblob from images where id=". intval($_GET["id"]); $rs = mysql_fetch_array(mysql_query($query)); //echo mysql_error(); echo base64_decode($rs["imgblob"]); ?&gt; </code></pre> <p>After a search there is a list of images that looks like </p> <pre><code>&lt;a class="lightbox" href="showimage.php?id=1" title="" &gt;&lt;img src="showimage.php?id=1" /&gt;&lt;/a&gt; </code></pre> <p>I use lightbox to resize the image on click. So i need to get the size of the image source (showimage.php?id=1).</p> <p>I have the following code snippet</p> <pre><code> $('a.lightbox').each(function() { var img = $(this).children("img"); var theImage = new Image(); theImage.src = img.attr("src"); $(this).fancybox({ 'transitionIn' : 'elastic', 'transitionOut' : 'elastic', 'speedIn' : 600, 'speedOut' : 200, 'overlayShow' : false, 'type' : 'iframe', 'width' : theImage.width + 20, 'height' : theImage.height + 20 }); }); </code></pre> <p>These function doesn't work all time. Often the resize image is very small. I don't have any idea to fix it.</p> <p>Here is a sample gallery <a href="http://www.phyxius.de/projects/phx.imga/" rel="nofollow">www.phyxius.de/projects/phx.imga/</a></p>

    2. COuse php to get the size. Image has to be fully loaded in browser before dimensions can be obtained with javascript. php can have them long before that. Add the dimensions to a `data-` attribute and extract from that for your lightbox

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
