Thanks for your patience. The new UI framework is in. Please do some testing and I'll write up some quick docs on how to write your own ImageGallery UI. I think you'll really like the API I've created. Lots of room for expansion, too.
Also, syndication of recent images is now available on all page types via a decorator.
$RecentImagesGallery (will show 5 images from the one gallery in your site tree)
$RecentImagesGallery(10) (will show 10 images from the one gallery in your site tree)
$RecentImagesGallery(5,some-gallery) (will show 5 images from a specific gallery, as referred to by URLSegment)
Yeah, I'm anxious to get some docs written. The GalleryUI stuff is pretty much self-documenting if you just poke around, but it would be good to have a tutorial. I'd love to have a setup where several members of the community are contributing new UI options.
Uncle Cheese, is there a way to modify $RecentImagesGallery(5,some-gallery) to pull the imagegallery from this page's child? I have a page and a subpage under that page that has a gallery. How can I get this to call whatever gallery is in it's subpage?
