Ability to keep lower resolution images on phone after upload

After an image has auto uploaded, it would be nice to let me keep a lower quality version locally on my phone, with exact same path as the original. This way I could use normal gallery app on my phone to browse all my photos, without thinking too much about storage use.

This would not be the same as using the app to browse images, as that needs to fetch the thumbnail/preview from server. What I am asking for is to generate that locally before deleting the uploaded image to server.
