I don't know how it happened, but the smileys from one of my forum are gone. I think they disappear after and update, I am not sure. Where are the smiley images supposed to be and why are the ones on my other updated forum not as cool as these on this forum?         

Thses have more of a 3D effect.

The smilies are always in "ip_root/images/smiles" folder, I don't know why you've got not cool ones...
