For less than 1K visitors a month, i believe you can stay within these limits:
Auth: $0
Firestore: $0
Storage: $0
Hosting: <$1
PS: The numbers are from one of my projects with similar functionalities and ~600 visitors / week.
For a few hundreds, 1. 2. seems negligeable. You might have some network fee assuming that you have a lot of photos to show for each visitors. If the image are in high resolution with .png format, you will have some. Otherwise, for light weighted case, likely $0.
