I was wondering... there are a few plugins out there which let you change your default smilies. Reading the comments for these releases it seems like trecherous buggy waters to venture into. Another page had a long explanation on how to change your config php file to show different smilies.
Question: Isn't it possible to just change the images in the smilies folder? Or do they have to have the same byte size or something like that? Seems like such a simple thing but I don't know how the smilies work and I'm nervous about screwing up something important.
