Those show up just fine, yeah! I can see them in Google Drive; I only pointed it out because it might be better to host them somewhere where they display for all users.
Also, Luis, do you mind if I steal one of those smilies for the Number of Character Appearances thread? Her current smilie there is just as outdated as the one over here.
I tried that on both my iPhone and MacBook Pro, yes. Didn't work.
That was with Chrome. On Firefox they simply don't appear at all, not even as null symbols. (The smilies in the OP show up just fine everywhere, FWIW, so this is a problem specific to these new Serini pics.)
