First off, Yarr! Secondly, I was thinking about mentioning Discord as well. Its voice/video functionality beats ROLL20 hands down, IMHO. No background music, most GM use ROLL20 for that. (Some are big on background music, but personally I find it distracting, ) Discord is pretty straightforward. You can create categories and sub-categories (IE channels) like in a forum (right click down arrow next to server name, and control the rights as to who can post (So you can have a GM only thread for GM commentary and world background. Just right click gear icon next to o channel name>Edit Channel>Permissions) and pin posts. Posting picture is drag and drop and you can post video by pasting the URL. Oh, and click the blue "Invite People" and post the invite URL here so we can join your server!
