For binary data, use a file bases approach. If you want to manage them with a database (i.e. Core Data), just store the filenames and any meta data you want to handle in the database.

SQLite supports blobs. I don't know the wisdom of using it as an actual store for image data--I imagine its performance would depend a lot on the real world particulars of your usage--but it's an option.
