power gallery designs do not support mobile devices.
the gallery creates an rss fead using the mediarss.php file of the images for the gallery.
you may be able to use this in another gallery, but this is not necessarily supported.
the mediarss.php file takes a querystring variable named gallery to determine which gallery to return images for:
mediarss.php?gallery=1
you will need to hand code any integration of the mediarss feed to your gallery
