This may not work for either of you, but all I needed to do was reverse the order. The default order is oldest -> newest. Since I have already had to hack this plugin to remove TimThumb, I figured I might as well hack it some more. Hopefully this or a more-robust solution can be added to the next version. (Eh, @johnnypeck??)
To add an “order” attribute to the shortcode that can reverse the gallery order, you’ll need to edit /wp-content/plugins/tag-gallery/tag-gallery.php in the following ways:
Around line 60, add this the end of the $defaults array:
'order' => 'default'
Around line 95, before “// Start the output of the tag gallery” add:
if ( $order == "reverse" ) {
$images = array_reverse( $images );
}
Now, to reverse the gallery order, just add ‘order="reverse"‘ to your shortcode like so:
[tag-gallery tag="my-tag" order="reverse"].
Remember that because “reverse” is the only meaningful value for the new “order” attribute, the following shortcodes all result in the default ordering:
[tag-gallery][tag-gallery order="default"][tag-gallery order="unicorns"] (or any other random word)
