Is it possible to show the image on the left and the description on the right. Currently, the description is on top and the image on the bottom. Also can you fix the size of thwe window displaying the image?
The function that renders the HTML for showing an individual picture is showPicture() in slooze.php. If you want it to generate different HTML you can just edit this function (or create your own, overriding version in slooze_local.php). If you want the description beside the picture you probably want a simple two column table, or a couple of <DIV>s and some CSS.
I'm not sure what you mean by fixing the size of the window.
