You're welcome.
Resetting network settings doesn't remove email addresses or your iCloud ID. It's not the same as erasing the iPhone. Your network settings (Wi-Fi, Bluetooth, ...) will be set back to default, and you have to set them up again.
If you're syncing your images via Wi-Fi, you won't need AirDrop very often, that's my experience. From time to time, I have to use it, because images don't sync, and I want to have them on my other device quickly, that's when I use it.
