I've been mucking around with FlickrViewer, and now have it working with flickr tags.

That is, if you supply a tag as a parameter to the php file, it will grab your photos from flickr with that tag. It's nice when you're tight like me and don't have a pro account :)

There's an example here:

I've also (kinda) updated it for SV1.8 - simply used the default index.html that comes with SV, renamed it index.php and replaced
fo.addVariable("xmlDataPath", "gallery.xml");   

with

fo.addVariable("xmlDataPath", "<?php print "flickrViewer.php?tag=" . $_GET['tag'] ?>");   

Seems to work well.

I'll let the author of FlickrViewer know, just thought I'd see if there was any interest in it here.
