smileys, images, thumbnails, etc on the side of post screen,

as u can see, there is alot of empty space on the side of message/post screen, is there a module or script that adds smiles thumbnails or small images that show in there and users can link to them in middle of their post by single click. if not that would be a nice addon on future release of minibb.

There is already a smilies plugin available on the download page
Just follow the instructions provided and edit the html templates to your liking.
