When I edit the diary entries, the picked image dissappears.

The application can't hold the image data of the original picked image. It disappears when the user wants to edit and have to pick the image again.

-(void)insertDiaryEntry {
    ZMCoreDataStack *coreDataStack =[ZMCoreDataStack defaultStack];
    ZMDiaryEntry *entry = [NSEntityDescription insertNewObjectForEntityForName:@"ZMDiaryEntry" inManagedObjectContext:coreDataStack.managedObjectContext];
    entry.body = self.textView.text;
    entry.date = [[NSDate date] timeIntervalSince1970];
    entry.imageData =  UIImageJPEGRepresentation(self.pickedImage, 0.75);
    [coreDataStack saveContext];

}
-(void) updateDiaryEntry{
    ZMCoreDataStack *coreDataStack = [ZMCoreDataStack defaultStack];
    self.entry.body=self.textView.text;
    self.entry.imageData = UIImageJPEGRepresentation(self.pickedImage, 0.75);

    [coreDataStack saveContext];
}
