@JLoon You can paste images using tinyurl.com and you can flag posts that violate standards as you see them.
Videos or songs can be posted by using the url and you can even use markup language for the link.
If I wanted to flag your post, I could use the little flag at the bottom right of your post that says, “Flag as…” You can then list the reasons you are flagging it and a moderator will mod it off or not when they see it.
Stick around kid, you might learn something.
