There is only one configurable Back Button in SimpleViewer-Pro.
However, you could link the 'Open Image in New Window' Button Bar button (and corresponding right-click option) to your PHP page.
Set showOpenButton="TRUE" in your gallery's XML file.
Set the linkURL attribute for each <image> tag in your gallery's XML file to be the URL for your PHP page.
Change the button's 'Open Image in New Window' rollover tooltip text to something more appropriate (such as 'Click to Download Zip File') using the languageList option, a description of which can be found in the FlashVar Options section of the SimpleViewer-Pro Config Options page.
Alternatively, you could overlay a link on top of the gallery by including code such as the following in the <body> section of your gallery's HTML index page. Note that for this to work, your gallery will need to have a transparent background. Please see this FAQ for details: http://simpleviewer.net/simpleviewer/su … ml#embed_6
<div id="overlay" style="position: absolute; top: 10px; left: 10px; z-index: 99;">
<a href="page.php">Click to Download Zip File</a>
</div>
