Handling ease of retrieval raw photos

[Zhiyuan-Amos]

Due to privacy concerns (so data is stored locally on mobile devices) and limits on storage space, photos are compressed. If the user wants to retrieve the image from his/her separate storage, it could be hard to find that photo.

1. One way is to store data on cloud, which is pricey.
2. Another way is to save & display the name of the file so it is easy to reference.
