The jack itself is still in place. You should do fine without the plastic insert. IMHO, locking RCAs can be a general pain sometimes. In the future I would make sure they are loosened all the way before trying to remove them.
BTW, there are a number of photo hosting sites that offer free accounts. I have been using Village Photos for a few years now. Because of my usage volume and patterns I've graduated to a paid account though, but free is still good for the moderate user. Its certainly better than using Facebook.
