You shouldn't be using both SWFObject and the object embed method. I would suggest removing the object embed code listed below. In addition to conflicts between SWFObject and the object embed method, your object embed method is using a fixed height and width.
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="800" height="600" id="FlashID" title="gallery">
<param name="movie" value="arch-gallery/simpleviewer.swf" />
<param name="quality" value="high" />
<param name="wmode" value="transparent" />
<param name="swfversion" value="9.0.45.0" />
<!-- This param tag prompts users with Flash Player 6.0 r65 and higher to download the latest version of Flash Player. Delete it if you don’t want users to see the prompt. -->
<param name="expressinstall" value="Scripts/expressInstall.swf" />
<param name="allowFullScreen" value="true" />
<param name="flashVars" value="baseURL=arch-gallery/" />
<!-- Next object tag is for non-IE browsers. So hide it from IE using IECC. -->
<!--[if !IE]>-->

You also have 2 SWFObject JavaScript file, you need to choose one and get rid of the other.
