dynamic smilies

[the geek]

you can try www.forumimages.com they are mainly an image site for phpBB, but I am positive you can use their stuf FOC on any site... just check the Terms & Conditions.
Their Smiles are pretty decent (though its not a massive collection)

Did you manage to find any smiles? I am looking for some as well.

Thanks.

Where might I find some smilies that are compatible with both Light and Dark Backgrounds? I have a light theme and a new dark theme on my site and our current emoticons aren't cutting it evenly
