hi.
thought i'd mention this here too since it will probably be useful for a lot of PaD galleries.
there are now some sequencing options on the gallery edit page to reorder images within a gallery. you can also set a gallery to have all new images appear at the beginning of a gallery instead of the end.
to make new images go to the beginning...
click the "sequencing" link on the edit gallery page
select "add new images to the beginning of the gallery" and Update Placement Settings
hope someone finds it useful.
