How do I permanently save changes to photos?

Question

The IOS 7 photo edit allows me to revert to the original photos after edits, which would be ok, if it didn't use the original when interfacing with other apps or when sending. For example, I cropped a lot of photos and then accessed the photos with my contacts app. The original unedited or uncropped photo showsl, not the edited or cropped photo. I searched for hours trying to find any comments on this topic. Nothing! Maybe everyone is excited about the new photo organization and forgot the basics. What good are editing features if the changes are not saved or accessible to other apps or when trying to send out the edited version?
I could find any way on Apple site or any on Google that tells me how to disable this feature or how to make changes to my photos permanent. Basically, what this means to me is the editing features are only useful if viewing from the photo app and not any other app or when trying to use the edited version.

The interface to share photos between your apps is the camera Roll. So to make your iPhoto edits visible to other apps on your iPad, share your edited version to the Camera Roll, when you are done with editing. If you have iPhoto on your iPad, you can save to the Camera Roll like this:

Save photos to the Camera Roll on your device
Tap one or more photos and tap
Tap Camera Roll.
Confirm or change the photos you want to share:
Select all the photos in an album or event: Tap All.
Select a range of photos: Tap Choose Photos, tap Range, tap the first and last photos in the range, and tap Next.
Tap Camera Roll.
To use your photo in another app, open the app and select the Camera Roll album.
