To upload media in Community Server you must first navigate to
the media section, once there you will see a link that says
'Upload'. Clicking on this link will bring up a menu where you can
select the destination media gallery.
Specify the file that you wish to upload and enter a name and
description. You may also tag the media item using the 'Tags' field
at the bottom of the page.
When you press the 'Specify File/URL' button a dialog box will
appear. This allows you to either upload a file from your computer
or link to a file that is already on the internet.
After uploading the media you will then be taken to a page where
you can view the added media object.
