Your embedding code looks OK.
PS any method to move from SW pro 1 to SW pro 2 ?
Your gallery already uses SimpleViewer-Pro v2.1.1. You can check the version number in the comments at the top of the 'simpleviewer.js' file.
Any special need to do it ?
The main advantage that v2.1 onwards has over v1 is Universal Playback: the ability to display the gallery on non-Flash-enabled devices.
As a SimpleViewer-Pro v.2.1.1 user, you can upgrade tot he current version for free by following the instructions on the Upgrading SimpleViewer page.
Please see the Version History for a full list of changes between versions.
In case you are not already aware, there is a SimpleViewer plugin for WordPress (WP-SimpleViewer) which will allow you to create and embed galleries directly in pages or posts from within the Dashboard without the need for any manual coding at all. You can download WP-SimpleViewer from its support page here.
Also, please take care when giving your gallery a percentage height. You may need to ensure that all parent containers of your gallery have been assigned heights via CSS. Otherwise, SimpleViewer might not be able to determine what its actual height should be. This can be difficult to do in a WordPress environment which is why the default height for a WP-SimpleViewer gallery is 600px (and not a percentage).
Please see the note regarding Using Percentage Heights here.
I hope these notes help.
