unfortunately gallery has stopped

[AC Question]

Getting the unfortunately gallery has stopped msg when trying to open gallery.
Have attempted to clear data and cache.
At a loss.
Any help would be greatly appreciated as I am not very tech savvy.

Welcome to Android Central! Which phone? Do you have an SD card inserted? If so, try unmounting it (in Settings>Storage) and see if the error continues.
