Pictures:Simple as usual. Copy link and surround with [img]Link (/img]tags
Where the "(" is really a opening bracket.
Bold: Works like Img tags just instead of those, use the letter "b".
Posting Videos from YoutubeType this : [video=youtube;
"Ending Half of Youtube Link"]"Full Youtube Link" (/video]
Where the "(" is really a "["
Now the "Ending Half of the Youtube Link" is what's shown inside of the red box outline of the picture above.
Begins after the first "=" sign and ends before the "&" sign.
The "full Youtube link" is represented by the black box which is from the beginning of the full link up till before the "&" sign.
Example 1: [video=youtube;RpLAs4VKVsg]
https://www.youtube.com/watch?v=RpLAs4VKVsg[/video]Your link would look like this if you were trying to put a video on Nexon Forums.
Long process >:U
