Welcome to Android Central! Using a file manager app, can you tell which directory those photo and videos are located? Make sure there isn't a ".nomedia" file in that directory.

By SD card local directory, do you mean the external microSD, or the "Internal SD"?

Also, what version of Android is the phone running?
