I just would like to give my vote for the importance of getting a way to order the pictures in an album without having to rename files or manipulating picture titles or date. And when you have put them in the right order they should stay that way regardless if the administrator changes the default sort order.
Or perhaps some sort of "lock picture order" could be possible? Then I could put numbers in the picture titles, sort by titles - and then "lock the sort" to keep the pictures in that order regardles on how I want to have it in other albums or what the admin wants to be the default way to do it.
If this thought applys to sorting albums in catgories too I haven't thought of, but manipulating this freely would be nice too.
