Can't download photos

[AC Question]

I am unable to open/download photos that have been attached to emails. This is a new problem. I have emptied the cache and uninstalled several unused apps on my phone. I have a Samsung Galaxy Core

Welcome to Android Central! I've seen a number of other threads about similar issues (but mostly about being unable to open attached PDFs). What happens when you tap the attached photo? Do you even see a preview?
