There's some things related to the Image Manager that we should investigate and potentially improve:
Do images stored maintain their metadata (e.g. geolocation)? If so we should remove those to protect user privacy, especially for when sharing is implemented.
Should we maybe compress images more aggressively? Most users would probably not notice some level of lossy compression, which could reduce backup sizes significantly. Even better if we can convert images to WebP though we should at the very least query support for that on the browser before doing so.
