photo folders

[GOBLINTIM]

I was wondering, i have folder i made on my mac, i call it, "apple wallpaper". i made my own wallpapers, so i got my brand new 4s, i synced it to my wallpapers folder, now when i look in my phone, i have two folders, photo library and apple wallpaper, both have the same pics in them. how can i delete one folder off my phone? the only thing that pops up in the photo library or wallpaper folder is to edit the pics, can not delete them.
