That's your call. If you're going to be storing 100gb of images then put them somewhere else, but this post is about using SQLite as a file format so storing binary files inside is not a problem.
We just transitioned our tiled images from using a directory structure to SQLite.
Having a single file per very large image (for mobile) makes transferring them to the phone over USB around ten times as fast. I wish I’d done it years ago.
- Direcory structure
- Zip file
- Tar file
- Sqlite db
Out of these, sqlite is the most compact, by far (also the fastest)
