Answer 1

Common technique for turning a UIImage into NSData is with one of the following two methods.

NSData *pngData = UIImagePNGRepresentation(myUIImage);
CGFloat quality = 1.0; // ranges from 0 to 1, 0% to 100%
NSData *jpgData = UIImageJPEGRepresentation(myUIImage, quality);

This of course assumes you know which type your image is. But since you used a PickerController to fetch the images, then it should be fairly easy to determine this. You just pull out the value under the key UIImagePickerControllerReferenceURL and check the ext parameter. This comment shows it visually https://stackoverflow.com/a/11506499/1529638.
