How do I edit an asset once I‘ve already uploaded it?

You can update any asset once it is in the system by locating the asset via the search option. Then clicking on the thumbnail to bring up the ‘Asset Details‘ page.

Users with the ability to edit assets (and all admin users) will be able to see an ‘edit‘ button next to the asset. This will take you into the asset where you can edit any of the metadata fields as required.
