Honestly I'd imagine its more of an issue of, with encrypt then send, the only way you can browse your remote files, is to download them and then decrypt them

so that means no browsing thumbnails of what could be a large collection, no viewing dates or other information on those files (since that is information leaked).

the only real way is to cache all that information on each device that would want to access those photos, which is doable, but it would feel a bit awkward, especially if sharing any of the data with other devices
