Currently "File Upload" does not designate the target album until the photos are uploaded, and we'd have to choose the album to put the photo to one by one. Not very intuitive as most users would upload photos album by album. It becomes hell when I have hundreds of albums and I'd have to locate the one I want thru an unsorted list.
I suggest an "Quick Upload to Album" button in Album List view, which leads to a normal File Upload page, except the target album is already known. I added the word "Quick" as I'd prefer editing the captions and descriptions later in a group, rather than one by one.
Just opinions from a frustrated user who just uploaded alot of photos.
