lmbbox

LMB^Box Smileys Plugin is for the Bloging System WordPress (www.wordpress.org). It is an easy 
way to add better smiley support to wordpress. WordPress has a smileys feature built in but it 
doesn’t let you click a link or button to see all the smileys available to the user. Now LMB^Box 
Smileys does this and more! You can have LMB^Box Smileys add a button to the Comment Quicktags Menu 
bar (LMB^Box Comment Quicktags plugin) or you can manually add a link to the smiles to your 
comment.php theme file. Either way, once you click on the button/link, a new window will popup 
and display the smileys page. You can edit the smileys page to display only certain smileys or 
all (more on that in the Installation part below). Also the smileys have css styles set and you 
can add the css tags to your stylesheet to see the results. One last thing, you can add your 
OWN smileys that you make, have, or found! More info in the Installation part below.
