Hi,
Google will index a page that contains a SimpleViewer gallery the same as any other web page. For example do a Google search for simpleviewer embedded example and the 1st hit is a page containing a SimpleViewer gallery. You can use all the usual methods to increase Google PageRank on a page containing a SimpleViewer gallery. Note also that Google is working on improving it's Flash indexing.
One thing to note is that Google may not index the gallery caption text since it is contained in an external XML file. To have the gallery caption text be indexed by Google, copy and paste the caption text into the gallery's HTML document inside the 'flashContent' div. The 'flashContent' div text is indexed by Google but is replaced with the gallery when viewed in a browser.
So in the gallery folder's index.html file, replace this:
<div id="flashContent">SimpleViewer requires JavaScript and the Flash Player.
<a href="http://get.adobe.com/flashplayer/">Get Flash</a></div>
with this:
<div id="flashContent">SimpleViewer requires JavaScript and the Flash Player.
<a href="http://get.adobe.com/flashplayer/">Get Flash</a>.
<p>Here is my gallery caption text for image 1</p>
<p>Here is my gallery caption text for image 2</p>
<p>Here is my gallery caption text for image 3</p>
<p>etc...</p>
</div>
