aha.. its probably because they are all animated gif..
msn doesnt let you use animated ones.. (not easily at least)
also, they have to be a specific height and width.. .so as long as you chop the MG smilie in the right place.. you can use it.....
EG
lets say this smilie -->

was too big for msn.. so you cut it in half... and insert the two halfs into msn... you call them using img1 and img2
so once you type
img1 img2 you will get the full
use a reasonably good image modifier program.. like photoshop or paintshop pro.. .(NOT MS PAINT!!!!!!) to cut the smilies up.
I hope something made sense in there.. if not try searching google for "how to insert smilies on msn"
