I think than 8.1 is back to the way 7.0 worked, at least with respect to manually synced photos. If you let iTunes sync them automatically then all bets are off. But if you sync photos manually into a folder on your computer, it loads them with whatever folder hierarchy you have there, and they appear in alpha order by title. If titled by your camera they are probably already in chrono order as most cameras assign ascending numbers. Otherwise you may have to use a program like Graphic Converter to rename (it will do them en masse). If you are on 8.0 iOS, then update - that version had a screwy way of organizing photos, user rebellion caused them to bring back the more traditional way in 8.1.
