  • You need to reduce image resolution. Say, going from 5MP to 0.3MP (VGA) would reduce memory usage more than 16 times.

    Image format does not matter as images are uncompressed as they are loaded into memory. Using compressed formats like JPEG can reduce amount of storage needed though.

    If your images are not under your control then you would need to use Imaging API to scale them down.
