Or at least fix the detach feature so every time you detach, you don't then go back to the first group of pictures.
To elaborate-- When you attach preexisting images to a page, you can attach up to 10 at a time by clicking on them and then hitting the attach command.
So why can't you do the same with detaching?
When you detach, you see all the photos in order of most recently attached. Say you want to attach the first and second of 300 photos. You have to click through 30 sets of 10 photos, detach one, and then do it all again because each time you detach, it takes you back to the most recent pictures first.
