Speeds up and beautifies your blog by substituting the individually-wrapped WordPress smilies with a single CSS image sprite containing all emoticons.
Speedy Smilies takes emoticons in WordPress to the next level (where it should be already and hopefully one day will). The end goal is to make smilies load faster in the browser for visitors and make them easy to insert into posts/pages for authors. In addition to the speed benefits, Speedy Smilies allows authors to easily change the appearance of emoticons using smiley sets.
