Boy, my mind isn't running on all clicks this morning... but do you see other post's smileys, or none at all? Do you see other's pictures in posts? If you don't see either, then you have your pictures turned off....
Ok... I'm not sure but maybe there is an option in your display... back on your mail page, side column? To block images?
There are plenty of ppl who can help you here.. hopefully they'll catch this thread and do so.
OH OH OH I found it! Go up into your Profile...the drop down... and EDIT DISPLAY...
