OK. So change to setting less than or equal to your php.ini setting for upload_max_filesize which must be >= than post_max_size integer. (Reference: PHP.net Reference)

My php.ini is set to 8M by default for both upload_max_filesize and post_max_size integer. File sizes larger than that, say 12M, I would need to change both to 12M at least. Trade off would be larger files in storage and slower browser loading speeds.

Got it.
