phpBB3 Allowed Attachments List MOD

A quick MOD for the phpBB3 posting form to display the allowed file extensions & filesizes for attachments.

MOD should take less than 5 minutes to do manually.
Files to edit are
posting.php
styles/prosilver/template/posting_attach_body.html

If a filesize has been explicitly set for a file type through the ACP it will use that value. If that value has been left at zero to denote no limit, it will use the servers' uploaded file size limit instead.



NOTE: Don't forget to Purge Cache via the ACP after making these file edits.
