Shoutbox

OK, now i dunno why this is happening so hopefully someone here will. When i add some custom emoticons that are *.gif, MSN always screws up the background. But only msn does, they are fine in Win P&F Viewer and they look fine in ImageReady too. So is there something i can do to fix it or am i doomed to never use it on MSN ?

Here's a screenie of what i mean.
