Autoviewer for 4images

[Alessio]

I'm going to install a viewer similar to Tiltviewer (http://www.4homepages.de/forum/index.php?topic=20789.0).
It's called Autoviewer: http://www.airtightinteractive.com/projects/autoviewer/index.html

I'm writing the file autoviewer.php that is very similar to tiltviewer.php.
I need to indicate the width and the height of the photos but I don't know how to do it.
http://www.airtightinteractive.com/projects/autoviewer/manual_instruct.html
Example:

Code: [Select]

<image>
<url>images/wide.jpg</url>
   <caption>This is a caption.</caption>
   <width>700</width>
   <height>465</height>
</image>
Here is my file autoviewer.php, could you help me?

Code: [Select]
