Saving blob data in NSUserDefaults will result a huge performance penalty for you app. You have two options:

1. Save image in cache folder as a file and use NSUserDefaults to store their path
2. Use CoreData, SQLite or Realm databases to store images. Data structure of your data will determine which one is more appropriate.
