I strongly suggest using files for caching images (and more generally for caching large files)... ;)

...and store the path/filename in database... Even if there is a way to store such blobs in sqlite, that would probably a potential performance bottleneck.

To reduce image sizes, you can easily compress to JPEG using UIImageJPEGRepresentation.

I strongly suggest using Core Data, so you don't have to care for how persisting of images/data has to be implemented.
