It seems that when I want to add a graphic or photo to our church website, it now must be uploaded to Media.
Within Sites, I can see what I have uploaded to Media through My Media tab. In Media, I can't see or manage what I have uploaded to My Media.
To manage what I have uploaded, I have to add or modify a graphic, click on Upload from Media before i can get to a place to delete old images I no longer need, or did not work when I saw them on the website.
