Hi, one of my administrators who uploads photos to our CPG actually had a pretty good idea.
In the Album Properties page (modifyalbum.php), you should offer an Image sort order:
Title Asc / Desc
Name Asc / Desc
Date Asc / Desc
Position Asc / Desc
There's one in Config for all albums, but an admin might want the control per album.
In our case, there are some albums that we consider 'permanent' so we want files from oldest to newest. Then we have some albums still being updated so we want to show newest first.
Otherwise, great job on CPG!
